NORMAN, Okla. -- It didn't take long for Oklahoma's three-way quarterback competition to be reduced to two.
Oklahoma announced Thursday that sophomore quarterback Kendal Thompson suffered a fractured right foot on the first day of practice earlier in the morning.
Instead, Thompson will undergo a surgical procedure to repair the fracture, which figures to sideline him for the rest of the preseason, and probably longer.
"We're optimistic that Kendal will return early in the season," Sooners coach Bob Stoops said in a statement. "He has a very positive outlook and is eager to rejoin his teammates on the field as soon as possible."
Though Bell has been viewed as the favorite to win the job because of experience, Thompson and Knight have each received equal snaps during the offseason. Thompson had a strong spring game performance in April, completing 8 of 15 passes for 86 yards and a touchdown.
Thompson, a left-hander, is the son of former Oklahoma quarterback Charles Thompson.
