Cornerback Chris Carr has been ruled out for Sunday's game against the Colts, meaning he will miss his third straight game with a back injury.
The status of both kicker Billy Cundiff and linebacker Ray Lewis is less certain.
Both Cundiff (left calf) and Lewis (toe) are listed as questionable on the final injury report of the week.
Head coach John Harbaugh said earlier today he's hopeful Cundiff will be able to play against the Colts. If Cundiff is unable to suit up, the team will likely sign free agent Shayne Graham to take over the kicking duties.
Lewis appears less likely to play. The 12-time Pro Bowler did not practice all week.
Center Matt Birk (shoulder), left guard Ben Grubbs (toe), cornerback Jimmy Smith (thigh) and running back Anthony Allen (hamstring) are all listed as probable for Sunday.
For the Colts, quarterback Peyton Manning (neck) has been ruled out, as has linebacker AJ Edds (ankle).
Starting tight end Dallas Clark (fibula), guard Joe Reitz (knee) and linebacker Pat Angerer (knee) are questionable.
