EAST RUTHERFORD, N.J. -- With the retirement of seven-time Pro Bowl defensive end Michael Strahan, the job of repeating as Super Bowl champions was going to be difficult for the New York Giants.

Now it might be near impossible with the news that fellow Pro Bowl defensive end Osi Umenyiora is out for the season with a knee injury.

An MRI on Sunday showed that Umenyiora tore the lateral meniscus in his left knee in a preseason game against the archrival Jets on Saturday night.

The two-time Pro Bowler will have surgery on Tuesday at the Hospital for Special Surgery in New York City. The recovery period is about four months.

Dr. Russell Warren, the team surgeon, never discussed a non-surgical option, coach Tom Coughlin said.
