What we know about the most important injuries that will affect the AFC South games Sunday:
Titans at Bills
Defensive tackle Jurrell Casey (shoulder) and middle linebacker Colin McCarthy (ankle) are both crucial components to the effort the Titans will need to stop the C.J. Spiller-Fred Jackson duo of Bills running backs. Both Titans defenders are questionable. Expect them to play, though they could be limited.
Ravens at Texans
Cornerback Johnathan Joseph (groin) was limited Friday. He will play, the question is how much and how effectively. The Ravens will likely test him early with Torrey Smith. Right guard Antoine Caldwell needs to take a concussion test to return, but they are listing him as probable, which suggests they are expecting him to pass.
Browns at Colts
Inside linebacker Pat Angerer (foot) will play for the first time this season, seeing time in the base package in a rotation with Kavell Connor and Jerrell Freeman. Out are defensive end Cory Redding, outside linebacker Robert Mathis, nose tackles Fili Moala and Martin Tevaseu, cornerback Darius Butler, running back Donald Brown. The collective hit to the run defense on a day when it needs to slow Trent Richardson is quite large. Left guard Joe Reitz (knee), yet to play this season, is questionable. If he’s out, Jeff Linkenbach’s been the replacement.
Jaguars at Raiders
Outside linebacker Daryl Smith (groin) remains out, and receiver Laurent Robinson (concussion) and safety Dwight Lowery (ankle) won’t play either. Chris Prosinski will start for Lowery, despite his tackling troubles in his work as the third safety. The other starting safety, Dawan Landry, is probable with a knee injury.
