Sophomore offensive tackle Kristofer Curtis will no longer play football for Syracuse after suffering an injury during the preseason, head coach Doug Marrone announced Wednesday.

Curtis’ injury was never disclosed, but he spent most of training camp working off to the side at practices with Will Hicks, assistant athletics director for strength performance. With Curtis’ medical history, Marrone said team doctors determined it was best to keep him off the field.

“I found out this afternoon, late, we had meetings,” Marrone said, “that our doctors recommended Kris, because of his medical issues, will not be able to play again.”

The 6-foot-4, 273-pound Curtis redshirted last season, but he was expected to compete for a starting spot on the offensive line this season.

Marrone was waiting to speak to Curtis’ parents before making the announcement, but Curtis tweeted about his future during the Orange’s practice Wednesday.

“I saw Kris just now. I said ‘Kris, why would you do that?’ He said, ‘Coach, I know, I made a mistake, I should’ve came in and spoken to you first,’” Marrone said. “So those things happen with kids and that’s the situation.”
