MANHATTAN, Kan. . -- Third-ranked Kansas States perfect season remained intact Saturday night. So did its national title hopes. The future of both may be in jeopardy, though, after Heisman Trophy front-runner Collin Klein left in the third quarter of a 44-30 victory very Oklahoma State with an undisclosed injury. Kansas State coach Bill Snyder declined to discuss the nature or severity of it afterward, and said he wasnt sure whether Klein would be available for next Saturdays game at TCU. "Obviously he was injured or we wouldnt have taken him out," Snyder said. Klein had thrown for 245 yards and run for 64 more before sneaking in for his 50th career rushing touchdown with 9:47 left in the third quarter to give Kansas State a 38-17 lead. It wasnt clear when he got hurt, but Daniel Sams played the rest of the way. "Without Collin at quarterback, we had to do some adjustments," said Tyler Lockett, who had a 100-yard kickoff return touchdown. "Collin was still a leader. He was on the sideline getting us going, especially when things werent going our way. Thats what I like about him." Oklahoma States Wes Lunt also left with an injury after throwing his third interception in the third quarter. The freshman quarterback, who missed six weeks with a knee injury earlier this year, threw for 184 yards and a touchdown before giving way to Clint Chelf. Cowboys coach Mike Gundy likewise refused to discuss his quarterbacks injury. "Im really disappointed in myself, in our coaches, in the way we played," Gundy said. "You travel on the road, and you play a good football team, and you turn the ball over, youre poor on special teams and you dont tackle well, you essentially dont give yourself a chance to win." Allen Chapman picked off three passes, returning one for a touchdown, and John Hubert added a pair of TD runs as the Wildcats (9-0, 6-0 Big 12) moved ever close to a Big 12 title. Perhaps a national title, too. They began the day second in the BCS standings behind only Alabama, which squeaked past LSU, and ahead of fellow unbeaten teams Notre Dame and Oregon. "Im proud of our guys because I think theyve held up under the pressure," Snyder said, "because it increases as you go on." Kansas State ended the Cowboys three-game winning streak and lock up its first win over them since 2006. The Wildcats have scored at least 44 points six times this season, and this time did it against a team that had allowed 38 total over its last three games. "It was a tough loss and everything, but they played great," Oklahoma State running back Joseph Randle said. "Theyre deserving of where theyre at, 9-0, and they played a great game." Chelf finished 16 of 27 for 233 yards and a touchdown for the Cowboys (5-3, 3-2), who should know something about playing late-season spoiler to a team in title contention. They were ranked No. 2 when they lost to Iowa State late last season, and got shut out of the BCS title game. This one was just about as wild as last seasons matchup in Stillwater, when the Cowboys held on in the final minutes after the teams combined for 32 fourth-quarter points. Oklahoma State struck first when Lunt hit Austin Hays for a 54-yard touchdown reception, but the Wildcats came back with 17 unanswered points -- Huberts two touchdown runs were sandwiched around the first of Anthony Canteles three field goals. Quinn Sharp added the first of his three field goals to get the Cowboys within 17-10 before the fireworks really started: Lockett field the ensuing kickoff deep in his end zone and went the distance for his fourth career TD return, and Desmond Roland answered by fielding a short kickoff by Kansas State and going 80 yards for another touchdown return. Chapmans pick-six made it 31-17 at halftime. The Cowboys had the ball to start the second half, and Lunt appeared to get hurt while throwing an interception to Nigel Malone. He never returned to the game. The Wildcats marched 93 yards before Kleins touchdown plunge from a yard out made it 38-17, but their star quarterback never returned to the game. Sharp and Cantele traded field goals before Chelf hit Charlie Moore for a 13-yard touchdown catch to get the Cowboys within 41-27. The two kickers traded field goals again before Cantele missed from 24 yards to give Oklahoma State the ball with 4 1/2 minutes left in the game. The Cowboys marched to the Kansas State 8, but Chapman picked off Chelf in the end zone for his final interception of the night. His three picks were one shy of Jaime Mendezs school record set against Temple on Sept. 26, 1992. "It came down to a couple possessions, and we turned the ball over, and youre not going to win like that," Chelf said. "We definitely had to play better than we did."

He practised springing up to throw after catching the ball, with no hesitation or signs that he had ever been seriously hurt. Posey showed he has plenty of pop in his bat, too. He cleared the fences a couple of times in his first round of batting practice at Scottsdale Stadium on Sunday, Day 1 for Giants pitchers and catchers. After bench coach Ron Wotus surrendered those home run balls, Posey quipped: "Four-seamer coming at 55 (m.p.h.), I tend to square that one up." Clearly, San Franciscos cleanup hitter is loose, good-natured and in a positive frame of mind. "It was special for me because Ive put in a lot of work to get back to this point and this is just another step," Posey said. "Theres still some work to do but I was very happy with today." More than 50 fans lined the fences throughout the ballpark trying to catch a glimpse of Posey getting back to work with the team at last. "For him, its an important day," reliever Santiago Casilla said. "Hes waited a long time to play. Hell be OK. Hes been working hard. Everybody wants to watch him." The 2010 NL Rookie of the Year made his highly anticipated return to the field in a formal setting after a season-ending leg injury last year. He tore three ligaments in his left ankle and broke a bone in his lower leg in a frightening home-plate collision with Floridas Scott Cousins on May 25. Posey is one of a handful of key major leaguers working back from injuries this spring -- including Cardinals pitcher Adam Wainwright, Colorados Jorge de la Rosa and reliever Joba Chamberlain of the Yankees. Through his entire ordeal, Posey has been able to reflect on his baseball career. Yes, he wants to keep catching for years to come, though changing positions did cross his mind a few times. He refuses to get involved in speaking out about the need for any rules changes when it comes to making contact with the catcher (manager Bruce Bochy is handling that campaign). Posey wants to do everything he can to stay in the lineup as a regular. "I think its just a greater appreciation for doing what I do, just enjoying this, being out here today catching a couple of pens and maybe some of the not-so-glamorous stuff of a catchers job," he said. "Enjoying that stuff a little bit more and just knowing that it can be gone quick." General manager Brian Sabean, Bochy and the brass kept a watchful eye on Posey in the bullpen. It was a monumental moment for Posey, whose long road to recovery included having screws removed from his surgically repaired left ankle in July and pushing himself around on a makeshift scooter to keep weight off the injured leg. Everybody is encouraged seeing Posey in uniform. "I threw to him Friday," left-hander Madison Bumgarner said. "He looked normal to me, ready to go, like he hadnt missed a beat." The Giants have a plan in place to keep Posey from overdoing it now -- and he understands that. [url=http://www.falconsofficialteamstore.com/autographed-jacquizz-rodgers-jersey... Rodgers Jersey. He will do all he can to avoid another injury that could derail his plan and force him to become a full-time first baseman. It would mean a lot to Posey to play in the first Cactus League game March 3 against defending NL West champion Arizona, and Bochy believes thats possible. For a while, Bochy will check in with the medical staff after each of Poseys games in which he catches five or six innings. Posey wont catch bullpens Monday but is expected to participate in other baseball activities. "Thats our decision, not his," Bochy said. Sabean watched Posey during the fall as he began catching again. "He thinks everything is fine," Sabean said. "Hes ready to get out here. Itll be us holding him back." These days, Posey said he consciously thinks about picking up his six-month-old twins -- daughter Addison and son Lee -- by squatting down first as to not aggravate anything. Its all of these little things he has learned through what became a painful blow to the Giants, who missed the playoffs a year after winning the World Series. After Lincecums session, the right-hander greeted his catcher with a friendly handshake and thumbs-up. "It just kind of picked up where we left off," Lincecum said. "Its nice having a chance to do that down here and just kind of having a clean slate and a new season to work with. Hes got a new season to work with. I dont think hes thinking about the injury too much." Posey has distanced himself from the collision -- though he has watched it multiple times -- and the emotional aftermath. Cousins has expressed how sorry he is the injury happened but called it an aggressive baseball play. Posey said Sunday he accepts that Cousins does care, even if they havent spoken despite efforts by the Marlins outfielder. "The biggest thing for me back then and now is looking forward and being positive and trying to get ready for another season," Posey said. Posey has regained his rhythm at the plate in a hurry. Even when he first started hitting last fall after about five months off, the swing came back fairly quickly. "Im blessed in a sense. I enjoy this game," he said. Poseys presence was missed every day last year. In 2010, he wasnt even called up from triple-A Fresno until late May but still batted .305 with 18 home runs and 67 RBIs in 108 games to help the Giants capture their first NL West crown since 2003. This is the player San Francisco gave US$6.2 million when he signed in August 2008 as the fifth overall pick out of Florida State, the richest deal ever for a Giants amateur. "I know theyre glad to have him back," Bochy said. "Hes very popular in the clubhouse and they know how long a road he had to endure in his rehab. Thats a tough road. The talent he brings makes us a better club." Not to mention all the other intangibles. "Busters the core of this team just because hes on both sides, offence and defence. Hes our leader," left-hander Barry Zito said. "Its good for the morale of the team. We feel like were a full unit again." ' ' '
