Leonard Hankerson has torn LCL

ASHBURN, Va. -- Washington Redskins receiver Leonard Hankerson will miss the rest of the season after tearing a ligament in his left knee. Hankerson will undergo surgery Thursday to repair the lateral collateral ligament.

It's the second time in three seasons that Hankerson's season has been cut short by an injury; he injured his hip as a rookie. In both cases he had just started becoming a bigger part of the passing game. This time, he had supplanted veteran Josh Morgan as the Redskins starting Z receiver and had caught 30 passes for 375 yards and three touchdowns.

Hankerson had caught a combined 10 passes in the two previous games before hurting his knee on a second-quarter catch against the Philadelphia Eagles on Sunday.

Morgan will return to the starting lineup, one game after being inactive for the first time in his one-plus years in Washington. Morgan has not been productive this season, with just 11 catches. He opened the season as the starter, but has only made two starts.

Others can play the Z spot -- against the Eagles, with Hankerson out and Morgan inactive, the Redskins used undrafted free agent Nick Williams and third-year receiver Aldrick Robinson in that role. Veteran Santana Moss can play that spot as well.

"I've got a lot of confidence in [Morgan]," Redskins coach Mike Shanahan said. "We've got some guys that we can flip-flop different positions if needed."
