Coach Nick Saban said it's possible a decision on Brown's status won't be made until game day.
"We will make a game-time decision on Ronnie's status, in terms of what he can or can't do and might even have to work him out before the game," Saban said Thursday. "We will see what he can do tomorrow and go from there."
Brown has 886 yards rushing on the season, 114 shy of the 1,000-yard mark. He should be able to get that if he plays the last two games, but getting 114 against New England -- even if the Patriots rest some players in preparation for the playoffs -- would be a tall order.

While Brown continues to sit out practice, WR/KR Wes Welker was back at work on Thursday. He remains listed as questionable, as are Channing Crowder and Gus Frerotte. But all three of them are expected to play against Tennessee.

Final note on the Pro Bowl teams that were announced on Wednesday. In addition to Zach Thomas, Chris Chambers and Jason Taylor being selected to the AFC team, TE Randy McMichael, P Donnie Jones and CB Sam Madison all were named as third alternates.
Any of those three would go to the game in the event of at least three injuries to AFC players at their position.
Speaking of injuries, don't be surprised if Taylor and Thomas both skip the Pro Bowl because of injuries that have hampered them for several weeks.
