Ulrich, who was from Azle, Texas, was hurt during a 49-14 loss to Ouachita Baptist on Saturday. The game was delayed for nearly an hour while he received medical attention before being transported to hospital. The school, a Division II institution in Bethany, Oklahoma, has not revealed the cause of death or the nature of the injury.
SNU Athletics announced the death on its X account: "It is with heavy hearts that we share the loss of our SNU football player, Tyler Ulrich. This loss is deeply felt across our campus. Our hearts are with his family, friends, teammates, and everyone who knew him. We ask that you join us in lifting them up in prayer."
Coach Dustin Hada wrote in a tribute on X: "Man of God, ultimate example of quiet strength, loyal, worker, joyous. That's who Tyler was!!"
School president Keith Newman said Ulrich died in hospital "surrounded by the love, prayers, and presence of his family, teammates and dear friends." A campuswide prayer chapel was held in Ulrich's honor on Tuesday.
Ulrich was in his third season at SNU, with 16 starts in 20 games, including six this year. He ranked third on the team with 36 tackles. Southern Nazarene has canceled Saturday's game at Southwestern Oklahoma State.
