JIM LEONHARD will be a sidelined spectator for another Jets playoff push.

The playmaking safety will miss the rest of the season with a torn patellar tendon in his right knee after being injured in Sunday's 37-10 victory over the Kansas City Chiefs. An MRI exam yesterday confirmed what the Jets first feared when Leonhard went down on a tackle following an interception.

"You feel absolutely terrible for him," coach Rex Ryan said.

It's the second straight year Leonhard has been lost for the season because of a devastating injury. Leonhard broke the same leg in a collision with teammate Patrick Turner during practice a little more than a year ago.
