Eagles wide receiver DeSean Jackson, who pulled out of the Pro Bowl with an unspecified injury, told the Philadelphia Inquirer on Thursday that he suffered a Grade 2 medial collateral ligament sprain and bone bruise in his left knee during a wild-card playoff loss to the Green Bay Packers.
Jackson injured the knee during the first quarter of the Jan. 9 game and was a non-factor after returning late in the first half.
Jackson hauled in 47 receptions for 1,056 yards and six touchdowns in 2010. He also ran for a touchdown and scored on a 65-yard punt return on the final play of the game to stun the New York Giants 38-31 in Week 15.
