Utah's standing in the Pac-12 South Division is even more precarious after the school announced Monday that quarterback Jordan Wynn will be out at least two to three weeks with the injury to his left, non-throwing shoulder he suffered over the weekend in a loss to Washington.

The Utes (2-2 overall, 0-2 Pac-12) play host to Arizona State ( 4-1, 2-0) on Saturday in a key South Division game. They play at Pittsburgh on Oct. 15 and at California on Oct. 22.

It's not even certain Wynn will be back at that point. Said a statement from the school: "He will be re-evaluated at that time to determine if he is ready to return."

The statement didn't identify the nature of the shoulder injury.

Wynn will be replaced by junior Jon Hays. He transferred to Utah this summer after the team he initially signed with out of Butte College -- Nebraska-Omaha -- dropped its football program.

He has played in two games this season, playing out the fourth quarter of Utah’s rout of Brigham Young on Sept. 17 and playing the entire second half of last week’s loss to Washington. He's completed 10 of 17 passes for 156 yards with a TD and an interception. His backup will be true freshman Tyler Shreve.

"[Hays] showed a lot of poise on a lot of plays," coach Kyle Whittingham said. "I saw a lot of positives in the half that he played. He has a strong arm and runs fairly effectively."

Whittingham added that the offense might get some tweaks. "We have to change some things in our offense to play to our quarterback's strengths," he said. "It will necessitate that we do some different things. We'll play more shotgun and more spread. We're working through that as we speak. Jon is a better runner than Jordan."

On the plus side, Whittingham also said he expects to get offensive tackle Tony Bergstrom, tight end Kendrick Moeai and tight end Jake Murphy back this week.
