Colorado football’s two-way Heisman candidate Travis Hunter left Saturday’s game against Kansas State with an apparent shoulder injury.

According to Brian Howell of BuffzoneHunter walked off the field twice with shoulder pain, the second time resulting in him walking out of the stadium to the nearby medical center at Colorado’s Champions Center.

Hunter left in the second quarter and did not return until halftime, leaving Kansas State up 14-7. He was declared questionable to return early in the third quarter, but was soon seen in uniform on the sideline.

The junior was part of the Heisman conversation because of his standout play on both sides of the ball. On offense, he entered Saturday 10th in the nation with 561 receiving yards and tied for sixth with six receiving touchdowns. On defense, he is a lockdown cornerback with three passes defensed and two interceptions this year.

That unique skill set makes him one of the toughest players in the country to replace, which Colorado may have to do if it wants to emerge with a win on Saturday. This injury could also represent the risks of Hunter’s workload, which has seen him play a total of 620 snaps in his first five games this season.

On Saturday, Hunter played 44 of the first 45 offensive and defensive snaps of the game.

Football is a notoriously punishing game and Hunter essentially tries to play two games a week. He missed three games last season after being injured on a foul hit last season and could now be dealing with another issue.
