Jordan Travis suffered what appeared to be a serious leg injury in the first quarter against North Alabama on Saturday night.

Travis’ leg appeared to be rolled up on as he was tackled at the end of a 17-yard run. He was immediately treated by medical personnel before being loaded onto the cart for further evaluation.

Here’s video of the injury (warning: it is graphic):

That is a devastating blow for Travis and Florida State. That injury has the potential to end Travis’ collegiate career as FSU was in the midst of a perfect season. Travis led FSU to a 10-0 start and a perfect ACC slate for the first time since the 2014 season.

Travis is Florida State’s all-time leader in touchdowns responsible for. He broke that record earlier this season.

As Travis was being loaded onto the cart, fans began chanting his name. Teammates and coaches were shown being emotional as he left the field.

Florida State was trailing North Alabama 13-0 at the time of Travis’ injury. He was replaced by Tate Rodemaker.
