FLORHAM PARK, N.J. -- Kris Jenkins' season is over prematurely -- again. In 2009, it lasted six games. This time, six plays.

Let the Albert Haynesworth speculation begin.

The New York Jets' nose tackle tore the anterior cruciate ligament in his left knee Monday night and will have season-ending surgery. An MRI Tuesday morning confirmed the team's fears. Because it's the same knee that required reconstructive surgery last October, Jenkins' career could be in jeopardy.

"Obviously, that's going to be a huge blow for us," coach Rex Ryan said.

Ryan said the Jets are interested in acquiring a veteran replacement, fueling talk of a Haynesworth trade. As of early Tuesday evening, the Jets still hadn't ruled out the possibility of trading for the Washington Redskins' disgruntled defensive tackle, but the chances it will happen are doubtful, according to a league source. But there is some interest in the talented but enigmatic lineman.
