Jets rookie quarterback Greg McElroy had surgery to repair his dislocated right thumb and the team says he is out indefinitely.
McElroy, the team's seventh-round draft pick out of Alabama, was injured when his hand hit the helmet of teammate Matt Kroul on a throw in the Jets' 24-14 preseason loss the Philadelphia Eagles on Thursday night.
After the game, McElroy said he had to pop his thumb back in after he was hurt in the second quarter.
He had surgery Friday morning, but the team says there are no immediate plans to place him on season-ending injured reserve.
McElroy was expected to be the No. 3 quarterback behind starter Mark Sanchez and backup Mark Brunell. The Jets could now be in the market for a third-string quarterback.
