LaDainian Tomlinson tweaks knee

LANDOVER, Md. -- LaDainian Tomlinson slipped awkwardly on the ground at FedEx Field in the first quarter of the Jets' 34-19 win over Washington on Sunday. The way he fell hurt the same left knee that forced him to sit out the last two weeks, but the Jets running back came back in the game and said afterwards that it is just sore.

Tomlinson doesn't expect to need any additional treatment and said he went back in because every player on the active roster has to be able to contribute this time of year.

"I have to battle through it because of the numbers situation," Tomlinson said. "If you say you're going to be active, you've got to suck it up sometimes."

The Jets running back had just caught a short pass from quarterback Mark Sanchez and was pushed out of bounds after gaining 16 yards. He tumbled over on the Washington sideline, and seemed to be in pain. He attempted to get up, but then fell back to the turf and waited for the Jets trainers. They assisted him off the field.

A few other Jets had to be tended to on the field. Running back Joe McKnight hyperextended his right elbow when a Washington player fell on it. He will have an MRI Monday. Antonio Cromartie returned kickoffs in his place.

Linebacker David Harris came back in the game soon after taking contact to the right ankle that has bothered him since last season.

"It's going to linger all season so nothing new," Harris said. "Just have to deal with it."

Calvin Pace briefly left the game with a calf cramp.
