For the record, Grizz at Blogging the Boys is on top of his game.
Florida Time Union reports that Stroud was on crutches during Thursday's practice and "seemed to be grimacing with each step". Rob Meier will take his spot of Stroud misses the game. Rob's a pretty capable DT himself.
What makes this critical is that behind Stroud and Henderson is Mike Peterson who is still questionable for the game. Losing Stroud and Peterson makes running up the middle a bit more attractive for Dallas. It also reduces the pressure we can put on Bledsoe. While not game changing per se, this is something to keep a close eye on.
