Not only did Ndamukong Suh's stomp against the Green Bay Packers cost the Lions when it happened, but it appears it will continue to have an effect on them in the coming weeks. The stomp drew a penalty that erased a stop on third down, and it also resulted in Suh being ejected. The Lions had to play the rest of the game without one of their best players, and now it looks like that could be the case for at least the next two weeks as well. From Adam Schefter:
Lions DT Ndamukong Suh is expected to be suspended at least two games.
If Suh is suspended for two games, he will be out next Sunday against the New Orleans Saints and two weeks from today against the Minnesota Vikings. Both of these games are extremely important for the Lions as they try to make the playoffs, and losing Suh would be a big blow to the defense.
It remains to be seen exactly how long Suh's suspension will be, but I think it's safe to say at this point he will miss some time because of what happened on Thanksgiving. I would imagine the NFL feels like the fines aren't doing anything to teach him a lesson, so suspending him is the logical next course of action. According to Jason La Canfora, even some of Suh's teammates think a suspension is "called for" based on what happened, and right now it looks unlikely that he will just receive a fine and nothing else.
UPDATE: Jay Glazer reports that the commissioner's office met this morning about Suh. Glazer is hearing that Suh could be suspended for one or two games, "but not more at this point."
