The Tampa Bay Buccaneers will miss at least three starters on Sunday. Vincent Jackson, Jacquies Smith and Ali Marpet missed their second consecutive day of practice, which means they're very unlikely to line up on Sunday once again. They'll likely be replaced by Donteea Dye, George Johnson and Evan Smith, respectively.
Austin Seferian-Jenkins' participation also continues to be in doubt. He was once again limited in practice today. Despite being close to returning the past two weeks, he has yet to fully participate in anything but Friday practices, which are generally oriented around walkthroughs. It's hard to say whether he'll play on Sunday -- one would think so, given that he was a game day decision last week, but we've been fooled before.
As for the Dallas Cowboys, Dez Bryant returned to practiced and should be ready for Sunday, as is the case for safety Barry Church. Christine Michael also returned to practice, as did Rod Smith. Both running backs should play on Sunday. Sean Lee is still out with a concussion, however, and if he can't pass the test before Sunday he won't be allowed to play.
