The Jets confirmed Mauldin's concussion and said he does not have any neck injuries. He will remain in the hospital overnight (Sept. 13, 7:39 p.m.).
Mauldin was at the bottom of a pile after a fumble in the fourth quarter of Sunday's game against the Cleveland Browns. Several other players appeared to fall on his head as he was on the ground.
"I'm very concerned right now not knowing anything," Jets coach Todd Bowles said after the game. "I'm very concerned."
Mauldin was on the ground for several minutes as medical staff attended to him. Players from both teams took a knee as he was down. He was taken to the hospital in an ambulance.
"It's tough, man," said Calvin Pryor, who played with Mauldin at Louisville in 2013. "I went out there to check on him. He still had his eyes closed at the moment. I wasn't able to say anything or get a response. I'm just praying for the best at this moment."
5:31 p.m.: The extent of the injury is not yet known, but as Bowles said, he is concerned for Mauldin and our hopes and prayers go out to him tonight in the days ahead. Mauldin is the type of person who has overcome such adversity in his life at a young age that you can't do anything but root for. I will root for his recovery from this injury. I'll put up a "get well soon" post for Mauldin and send your comments and well-wishes onto him through the team tomorrow.
