After losing another backup quarterback, BYU is scrambling to find a junior college player. Brett Salisbury left the school this week for personal reasons not related to football, Coach LaVell Edwards said.

The brother of Sean Salisbury, a former USC quarterback now playing in Canada, Brett Salisbury was heavily recruited out of southern California in 1986. He quarterbacked BYU's junior varsity as a freshman and recently returned from a church mission.Salisbury reportedly has no immediate plans for continuing his football career. His departure was not for any of the same reasons as Chris Hoge, who transferred to Ricks College for a chance to play, rather than back up Ty Detmer.

Salisbury and Brent Smith were sharing second-team duties behind Detmer in spring practice. Only Smith and Detmer remain for the last three weeks of spring drills, with freshmen Ryan Hancock and Brock Spencer reporting in August.

"It leaves us in a desperate situation," said quarterback coach Norm Chow, trying to sign a junior college player who could join the team in August and provide backup insurance. Smith, a 6-foot-4, 220-pound sophomore, is a walk-on who quarterbacked the junior varsity team in 1987 before leaving on a mission. "(Smith) has a good arm and is doing well, working with the second-team offense," Edwards said.

While missing one day's practice because of bad weather this week, BYU planned to work out today and Saturday to stay on schedule - eight sessions through two weeks, with 12 practices left, including the April 7 intrasquad game.

Reserve halfback Brad Clark is missing spring practice after suffering a broken leg in an auto accident. Tight end Chris Smith is being held out of some sessions following minor surgery on his elbow, and offensive lineman Scott Brumfield, a junior-college transfer, broke a finger in practice last week but is still working out, with a cast on his hand.
