Too big, fat, out of shape? Groin, hamstring, ankle?
Seems a lot like last year, without the suspension...

Marcell Dareus hurt his right ankle on the opening drive. He had it re-taped but was listed as questionable to return but did come back in the game late in the first half but was severely limited the rest of the way only playing 17 snaps. He is being evaluated and they will know more by Wednesday. 9/18
He can't make it through the opening drive 2 games into the season?
