USC Trojans’ Stafon Johnson may not be able to play again this season after he accidentally dropped a weight bar in his neck.

“It hit him with a lot of force, and it hurt him,” coach Pete Carroll said after the Trojans’ brief practice Monday night but before the surgery was finished. “No broken bones as far as I understand, but he’s got some damage in there somewhere, and they’re working it out, trying to figure out what it is. … It is serious. He did get hurt, so we don’t know exactly what it is, and they’re not going to know until they go through the surgery.”

An assistant strength and conditioning coach was standing over Johnson at the time of the accident.

“I’ve seen players have the bar slip and fall onto their chest, but never in my 25 years of coaching have I heard of someone dropping a bar on their throat,” said head strength and conditioning coach Chris Carlisle, who was standing 10 feet away at the time of the accident. “We’re fortunate he was being spotted.”

He was coughing up blood right away after the said accident. Reports said that he was bench pressing at that time when a weight bar accidentally slipped in his hand and fell onto his throat that resulted to severe injuries in his larynx. After having a seven hours surgery at California Hospital Medical Center, it has been reported that Stafon Johnson was already in stable condition but still couldn’t speak.
