EAST RUTHERFORD, N.J. -- Pro Bowl defensive end Osi Umenyiora was carted off the field in the second quarter of the New York Giants' annual preseason game against the New York Jets after his left knee "locked up" on Saturday night.

X-rays were negative but further examinations are planned Sunday, the team said.

The 26-year-old could not put any weight on his leg. He was helped off the field with his arms wrapped around the shoulders of two trainers.

The injury happened with 10:48 left in the half on an incomplete pass by Brett Favre on third down.

Umenyiora started all 16 games last season and had 52 tackles and a team-high 13 sacks in earning his second Pro Bowl appearance. He added seven tackles in the Giants' run to the Super Bowl.

The Giants are a bit thin at defensive end this season with the retirement of seven-time Pro Bowler Michael Strahan. Justin Tuck has replaced Strahan. New York also signed veteran Renaldo Wynn in the offseason.

If Umenyiora was sidelined for any considerable time, the Giants could move strongside linebacker Mathias Kiwanuka back to defensive end. He was switched to linebacker last year so the team could put its best 11 players on the field.
