Oklahoma quarterback Kendal Thompson started fall camp as part of a three-man competition for the starting job. That race narrowed on Thursday after Thompson suffered a fractured foot in the Sooners' first practice.
"We're optimistic that Kendal will return early in the season," coach Bob Stoops said in a prepared statement. "He has a very positive outlook and is eager to rejoin his teammates as soon as possible."
Thompson, the son of former Oklahoma quarterback Charles Thompson will undergo a surgical procedure to repair the fracture. He is expected to sit out the rest of the preseason, possibly longer.
With Thompson on the sideline, the focus turns to junior Blake Bell and redshirt freshman Trevor Knight. At Big 12 media days, Stoops took offense at the a question that insinuated Bell was "the guy right now." Many believe that Bell has the edge in the competition, but Stoops has been determined to keep the competition going.
The 6-6, 263 pound Bell has the advantage of experience, totaling 24 rushing touchdowns in the last two seasons -- mostly in the specialized goal line sets that helped coin his nickname, "The Belldozer."
Knight was a four-star prospect in the Class of 2012, he led the scout team last season while redshirting and split reps with Bell and Thompson during spring practice.
