"Sorry panther fans but it Looks like I'll be missing the game opener this year due to my recent ankle sprain! I'll be helping my team today by cheering them on! lets go panthers!! #panther-nation," Stewart wrote.
Stewart didn't practice all week, so the news isn't a surprise. He was listed as questionable for the Panthers' game against the Buccaneers. Tampa Bay had trouble stopping the run last season, so we expect to see plenty of Williams. Then again, the Bucs also had trouble stopping the pass. They had trouble with basically everything.
On Sunday, coach Greg Schiano can start to erase all of that.
UPDATE: Stewart is indeed inactive for Sunday's game.
