Taysom Hill will give his collegiate football career one more season, and is seeking a special waiver to pave the way.

Hill announced on his comeback on his Twitter account Tuesday afternoon, and ESPN's Brett McMurphy reported shortly after the BYU quarterback would seek a medical waiver to give him one last season of eligibility.

Hill has played four season at BYU, though three were shortened by injuries. Hill received Heisman Trophy consideration for his 2013 season in which he threw for 2,938 yards and ran for 1,344. That season alone he played in all 13 of BYU's games, whereas he played in a combined 12 games the other three seasons.

This past season Hill only played in the team's season opener, but left the game early after injuring his foot. Tanner Magnum took over at QB and memorably won the game with a walk-off Hail Mary touchdown pass.

Magnum finished his freshman season with 3,377 passing yards and 23 aerial touchdowns. According to ESPN, BYU offensive coordinator Ty Detmer confirmed Hill and Magnum would have to vie for the starting QB position in an open competition this spring. Detmer will reportedly implement a pro-style system at BYU this season, though that will not give Magnum, a pocket passer, a leg up in the competition.

"No. 1 is keeping the quarterback healthy, whoever that is," he told ESPN. "I don't envision him running as much as he has in the past, but you never know when the game starts. He'll have some opportunities. Just him back there kind of with the threat of that, kind of keeps people at home on the back side of the run game and some of those things.

"We'll tailor our system to what the guys do best, but at the same time try to keep that quarterback healthy and out of harm's way as much as we can."
