The Dolphins started this game without Phillip Wheeler.
But after the first quarter they had lost both Koa Misi (ankle) and Dannell Ellerbe (hip) were both out of the game due to injuries. Both were reported as being questionable to return.
[Update: Misi will not return to the game, according to the Dolphins.]
That put Jason Trusnik in the game. That put Chris McCain in the game. That put Jelani Jenkins in the game.
On the other hand, McCain blocked a punt three minutes into his first NFL game. So maybe getting him in the game isn't so bad.
