While Simmons' injury does not involve a fracture, Simmons said it's a really bad sprain and will preclude from doing anything football-related until January.
Simmons was replaced Sunday night by Kendall Newson, but he might have blown his chance to assume those full-time duties by muffing a punt in Dolphins territory.
There is the possibility that Terrell Buckley could be used in that capacity, but Coach Dave Wannstedt seems to be inclined to abstain from using players who play large roles on offense or defense.
So don't be surprised if Rogers is back there returning punts against Dallas.
Also on Tuesday, the Dolphins activated defensive end David Bowens off the non-football injury list.
Today was the deadline to do so; otherwise, Bowens would have had to remain on NFI the whole season.
To make room for Bowens, the Dolphins placed rookie wide receiver J.R. Tolver on injured reserve.
This concludes a bizarre season for Tolver, who showed a lot of promise during training camp but never got in a game in the regular season despite the team's well-document problems at wide receiver.
