OAKLAND -- Antonio Cromartie's bad day at O.co Coliseum on Sunday included a trip to a local hospital.
The New York Jets' cornerback suffered an injury to his ribs in the second half of their 34-24 loss to the Oakland Raiders and was taken after the game to Eden Medical Center for further evaluation. He flew back to New Jersey with the team.
The team called it a rib injury, giving no other details, but a league source confirmed reports that Cromartie suffered a bruised lung. He was in severe pain after the game and didn't talk to reporters. The chances of him playing next Sunday night against the Baltimore appear highly unlikely.
That means the Jets could be down two of their best players, Cromartie and center Nick Mangold (high-ankle sprain), who didn't travel to Oakland. Mangold is improved and there's a chance he could play in Baltimore, a source said.
"We're not sure about it right now," Jets coach Rex Ryan said of Cromartie's injury.
This was a nightmare game for Cromartie, who was penalized four times for 46 yards -- two pass interference and two holding calls. This came five days after Cromartie, courted by Oakland in free agency, declared he's a better playmaker than former Raiders and current Eagles cornerback Nnamdi Asomugha, still popular in the Bay Area.
"He did (have a tough game)," Ryan said. "Sometimes those things happen. They were running a bunch of double moves on us."
Cromartie also provided some fodder for the blooper reel. Late in the third quarter, with the Jets down by seven points, he fumbled a kickoff. But it wasn't just a fumble. He muffed it at the goal line, and when he tried to pick it up, he ended up kicking it forward about 10 yards. He tried again to pick up and he fumbled.
The Raiders recovered at the 12, and ended up scoring to take a 31-17 lead.
Ryan hinted that when Cromartie is healthy, his days as a kickoff returner might be over.
"That's something we'll look at," he said.
This has been an up-and-down season for Cromartie. He allowed two touchdown passes in the season-opening win over the Dallas Cowboys, but came back last week with two interceptions against the Jacksonville Jaguars, winning AFC Defensive Player of the Week.
