Tumua Fagota Siaumau apologized to the coach, Darius McCormick, during his sentencing Monday, The Salt Lake Tribune reported. McCormick coaches at Granger High School in West Valley City.
"I ask that you forgive me," Siaumau said, kneeling before the victim.
McCormick said he still has trouble forgiving his attacker. His jaw, broken with a helmet, is now held together with two steel plates and eight screws.
"You try and get over the anger," he said. "But when my jaw pops and clicks, the same emotions come up."
McCormick said he tried to intervene when he heard Siaumau screaming at his son in Samoan after the Granger team lost its fourth consecutive game in September.
