PROVO — Junior Tom Sorensen, projected to be BYU's starting center this fall, is expected to be out 4-6 weeks due to a shoulder injury, coach Bronco Mendenhall announced after Tuesday's practice.

Sorensen is scheduled to meet with a doctor today.

"We're anticipating surgery. That will estimate him being out 4-6 weeks," Mendenhall said. "The pain was not allowing him to be effective in our eyes nor his. I gave him yesterday to kind of try to sort through it as you build up what you expect to happen in a year and then it doesn't necessarily go like that. We'll find out today the severity of it and the time frame."

In Sorensen's place, the Cougars are looking at Dallas Reynolds, who is an All-Mountain West first-team performer at left tackle, sophomore Garrett Reden and junior R.J. Willing.

"We're still considering Dallas Reynolds as a possibility. We'll fill in the best five," Mendenhall said. "The good news is, they're all good players. It's going to be what unit, which five, works best together."

Sorensen was projected to replace two-year starter Sete Aulai, who graduated. Sorensen saw action in seven games last season.
