Carson Palmer reportedly hurt his throwing shoulder during Cincinnati's 27-21 loss to the Pittsburgh Steelers last Monday Night.
The injury was severe enough to keep Palmer out of practice on Wednesday and Thursday last week heading into Sunday's game against the Colts. Eventually getting on the field on Friday, Palmer ran a few drills and threw a few passes and listed as probable.
Due to the shoulder injury, Palmer "took a pain-killing injection in shoulder to help him start" against the Colts on Sunday. Even though miscommunication and bad decision-making ended up being a massive detriment during Cincinnati's 23-17 loss to the Indianapolis Colts, arm strength was hardly an issue with Palmer attempting several deep passes to Terrell Owens and Chad Ochocinco.
