• According to a report, Falcons cornerback Dunta Robinson is being evaluated for a possible concussion. Not the news you want to hear as you head into the playoffs. UPDATE: Robinson is out for the rest of the game with his head injury.

• Steelers guard David DeCastro has left the game with a stinger. His return is questionable.

• Bengals safety Chris Crocker has a right quadriceps injury. His return to the game is doubtful.

• Eagles linebacker Casey Matthews has a concussion, and his day is done.

• Ravens tackle Kelechi Osemele has returned to the locker room with a member of the team training staff.

Including quarterback Matt Ryan. UPDATE: According to CBS Sports' Jason La Canfora, Abraham is expected to be OK.
