Anquan Boldin cleared for practice

Renowned surgeon Dr. James Andrews has cleared Baltimore Ravens receiver Anquan Boldin to practice and possibly play Sunday against the Cincinnati Bengals.

He's listed as doubtful coming off knee surgery but there is an outside chance of him playing, the team said. Boldin practiced Friday.

Ravens coach John Harbaugh had said Boldin would miss the final two weeks of the regular season but would be able to return for the playoffs after having surgery Dec. 22 to deal with slightly torn cartilage. The Ravens did not reveal which knee was injured.

The 31-year-old Boldin has 57 receptions for 887 yards and three touchdowns this year.

Also for the Ravens, linebacker Dannell Ellerbe (concussion) and guard Marshal Yanda (chest) are doubtful. Cornerback Cary Williams (concussion), defensive end Cory Redding (ankle) and kicker Billy Cundiff (calf) are questionable.
