"It wasn't an impact injury at all," Cromartie said. "Something I just planted wrong, and it gave out on me a little bit."
It is not a new injury for Cromartie, who first broke his right hip in 2008 when he was with the San Diego Chargers. Since then, Cromartie's name has occasionally shown up on the injury report, but this appears to be a more persistent problem. He first mentioned that his hip was painful in September, and noted that he'd had the issue since training camp.
"It's the first time really this season, during my career, that it's bothered me this much except when it happened in 2008," Cromartie said. "It's just a point of seeing what's going on with it and go from there."
Statistically, Cromartie hasn't been as dominant a cornerback this season. On Sunday, he gave up a 60-yard pass to Torrey Smith, his sixth pass of 43 or more yards this season.
"That same nagging injury," Cromartie said. "The biggest thing is just see what's going on with it, keep trying to rehab it."
New York coach Rex Ryan referred to the deep ball as the Jets' "Achilles' heel" on Sunday. Part of that is due to the way Cromartie has struggled. Cromartie received less attention when former Jets corner Darrelle Revis played alongside him and generally took an opponent's top receiver. But last year, Cromartie played well after Revis was injured.
Cromartie wasn't the only Jet who was injured in Baltimore.
Jets running back Chris Ivory sprained his left ankle on his first carry of the game. Although that play was for no gain, Ivory went on to accrue 35 yards on nine carries.
