New York Jets cornerback Antonio Cromartie suffered a non-contact knee injury in practice Thursday, and the Jets are "concerned" it could be a serious injury.

ESPN New York's Rich Cimini reported Thursday night that Cromartie was taken for an MRI exam on the knee, citing two league sources. One source told Cimini that the injury was a hyperextension.

The loss of Cromartie, who made a Pro-Bowl appearance last season, would be a significant blow for a 3-2 Jets team riding the wave of a surprisingly strong early start to the season. Cromartie is their No. 1 cornerback, almost always assigned to the opposing team's best receiver.

Dee Milliner, the team's first-round pick in this year's draft, has missed the past two games with a hamstring injury. Their top two healthy cornerbacks are Darrin Walls, who has started the past two games in place of Milliner, and nickelback Kyle Wilson.

Cromartie, 29, has been with the Jets since 2010. He has 13 tackles and one forced fumble this season.
