RALEIGH, N.C. North Carolina State quarterback Grayson McCall announced his retirement from football on Wednesday night, less than three weeks after a vicious hit knocked him out of a game for the second time this season.

McCall was a sixth-year player who was a graduate transfer following a record-setting five years at Coastal Carolina, where he threw for more than 10,000 yards but also had concussion issues.

McCall was knocked out of the Sept. 14 game against Louisiana Tech and, in his first game back, left the field on a cart and was taken to a hospital for evaluation after a helmet-jarring hit in the first quarter against Wake Forest on Oct. 5.

As you all know I have battled injuries my whole career, but this is one that I cannot come back from, McCall wrote in an Instagram post. I have done everything I can to continue, but this is where the good Lord has called me to serve in a different space. Brain specialists, my family, and I have come to the conclusion that it is in my best interest to hang the cleats up.
