McElroy, a seventh-round draft pick out of Alabama, was injured when his hand hit the helmet of teammate Matt Kroul on a throw during the Jets' 24-14 preseason loss to 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.
The Jets announced McElroy had surgery Friday morning, but added there are no immediate plans to place him on season-ending injured reserve.
"It's just so frustrating," McElroy said after the game. "It's just one of those things. We play a sport, in this game, injuries are part of it. You never want to get too down because it can happen to anybody. I've been fortunate enough to stay healthy throughout my career."
Be sure to catch the "NFL Total Access" roster cuts special on NFL Network, 7 p.m. ET on Saturday.
The Jets will not officially announce their cuts until Saturday night, but the agent for offensive lineman Nevin McCaskill and linebacker Joey LaRocque said on Twitter that his clients had been among those released. "Solid players who should be somewhere soon," Paul Sheehy wrote on his Twitter page.
