Team physician, Dr. Ned Amendola, will perform the surgery on Gray's right knee next month. The senior letterman is expected to recover completely, following rehabilitation, and will petition the NCAA for a sixth year of competition.
"All of us share Lee's disappointment of not being able to play next fall," said Head Coach Kirk Ferentz. "The key thing for Lee to focus on now is finishing his academic work in a quality fashion and working hard to get back on the field in 2006. This is a tough setback for Lee but I am confident he will handle it well in the long run."
Gray started 11 of 12 games for Iowa at left offensive tackle last year.
