Wow, Jason Allen actually was out on the field on defense this week. I wouldn't say that he "played defense"...he did have two tackles...but then again, he was one of the players covering Donald Driver on the TD pass shown here.
Funny thing about that play: two referees came in and said the ball hit the ground. It sure looked to me at the time as though the ball came out, but on the replay it was hard to tell. How the ref saw enough in the replay to overturn the call is beyond me.
