Felix Jones (ankle, forearm), Marc Colombo (back), Terence Newman (rib muscle strain) and Bradie James (knee) returned to practice for the Dallas Cowboys on Thursday, according to ESPNDallas.com's Tim MacMahon. I would expect all four of them to play in Green Bay on Sunday, although Newman's injury will be monitored closely and the Cowboys will have some recourse in rookie Bryan McCann if he's not ready to go.
The Cowboys don't really have a great Plan B for Colombo right now, as evidenced by Alex Barron's performance earlier this season. I fully expect running back Tashard Choice to get some more carries against the Packers, but then, I've had that feeling before and it didn't end up happening.
The Packers shut out the Jets this past Sunday, so it's likely the Cowboys defense will have to have a good game against Aaron Rodgers. I'm not sure I like the chances of that happening right now; not with the way DeMarcus Ware and Anthony Spencer have struggled getting to the passer.
