Arch Manning, nephew of Eli and Peyton, scored five TDs in the dominant Texas win

In Texas, the Arch Manning Show lifted the curtain on Queen Yers' injury. The quarterback from one of football's most storied families threw for four touchdowns and ran 67 yards for another score after taking over for Years in the second quarter, leading the No. 2 Longhorns to a 56-7 victory over UTSA on Saturday night.

Texas (3-0) was leading 14-0 when Ewers suffered what coach Steve Sarkisian called an abdominal strain. Manning threw a 19-yard touchdown to DeAndre Moore on his first play, then broke a long sprint for another touchdown on Texas' next possession, as several UTSA (1-2) defenders chased him.

“When the adrenaline kicks in, it helps you run a little faster,” Manning said.

Manning connected with Isaiah Bond for a 51-yard TD on Texas' first series of the third quarter that made it 35-7. His next throw was a 75-yard deep strike TD to Ryan Wingo. He completed 9 of 12 passes for 223 yards and left the game after his final touchdown pass to Jonte Cook II in the fourth quarter.

“It helps when you have great players and good coaches around you,” Manning said.

The five-star recruit with an NFL family pedigree is the nation's highest-profile backup. With sharp passing and an unexpected burst of speed, Manning showed he really deserves the hype.

Manning is the son of Cooper Manning, the grandson of Archie Manning and the nephew of Super Bowl winners QB Payton and Eli Manning.

And if Ewers is out for an extended period, Texas still has time to develop Manning into a starter before the schedule gets tougher. Texas hosts Louisiana-Monroe next week, then opens its first SEC schedule at home against Mississippi State on Sept. 28. The Longhorns have a week off before their annual rivalry game with Oklahoma.

Texas did not immediately announce how long Ewers, who entered the game as the favorite for the Heisman Trophy, would be out. Sarkeesian noted that Ewers' injury was not caused by contact.

“The seriousness of this remains to be seen. We don't think it's anything structural or broken,” Sarkisian said.

Ewers had just completed a 49-yard pass to tight end Gunnar Helm on a deep throw and then handed off to Quintrevion Wisner before lying on his back waving to the team medical staff. Ewers eventually walked off the field but pulled his shirt over his face as he made his way to the medical tent. By the third quarter he was on the sideline in street clothes.

Manning called Ewers one of his best friends on the team and noted that the two are roommates when the Longhorns are together the night before games.

“I learned a lot from him,” Manning said. “He's a man to me, and I hope he's OK.”

Sarkeesian praised Manning's poise in the moment.

“It's tough when you have backups that don't have a ton of experience. Arch was our third guy last year,” Sarkeesian said. “There's nothing like being in a game. Playing in front of 105,000 people is not the easiest thing to do. I'm really proud of Arch.”
