Suh, a Detroit defensive tackle, was called for an illegal low block against Minnesota center John Sullivan during an interception return Sunday. The Lions won the game 34 24.


Suh said he wasn't going after Sullivan's knees, adding the two spoke about it at halftime. Sullivan said the hit was part of the game and it was penalized.


The NFL fined Suh $30,000 last year for unnecessary roughness because he kicked Houston quarterback Matt Schaub in the groin area.
