Ty Detmer, in a move that caught BYU officials somewhat by surprise, underwent surgery for his right shoulder Friday in Texas.

"Everything went well and he will be back in school next week," BYU Coach LaVell Edwards said. "Ty will be back throwing in three months and everything will be fine for the fall."Detmer went to his home in Texas right after last Saturday's Sea World Holiday Bowl. BYU's Heisman Trophy quarterback had both shoulders separated and was forced to come out of the 65-14 loss to Texas A&M early in the third quarter.

"We did not know about this to be honest with you. We did not know he was getting it (surgery) done. We knew he was seeing doctors in Texas. We knew he'd be checked over the weekend," said BYU trainer George Curtis.

Dr. Robert Jackson, one of BYU's three orthopedic surgeons, said Detmer suffered a grade 3 or complete separation of the AC (acromion clavicular) joint when he was hit in the third quarter. At first it was reported that Detmer was just going to rest the shoulder. Jackson feels Detmer did the right thing by having it operated on. "The feeling around the country is kind of split," he said. A lot of people favor rehabilitation while others feel surgery is better, he added.

"He went to an orthopedic shoulder specialist in San Antonio and had it repaired today," Jackson said. "It's an injury that should not do anything as far as hampering his ability to throw." It shouldn't affect his velocity or power, either, he added. "It's a fairly common injury in quarterbacks. It's just like Troy Aikman's."

It will be six to nine weeks before Detmer can throw the ball again, Jackson said.

Both Jackson and Curtis said it was an injury far less serious than the one quarterback Robbie Bosco suffered in 1985.

"Robbie Bosco had an injury to his rotator cuff and shoulder joint. This (Detmer's injury) is above, on top of the shoulder. It's not in the shoulder itself," Jackson said.

"The ligament was torn and was just hanging down . . . the feeling was that because he is a thrower, he needed to have it repaired," Curtis said.
