Receivers Trey Franks and Jaz Reynolds, wideout Kameel Jackson and defensive back Quentin Hayes received the suspensions, a news release from Coach Bob Stoops said Wednesday. The rule violations were unspecified.
The sports Web site OUInsider.com reported that Franks' penalty is for the entire 2012 season, and Reynolds' for seven games.
Franks and Reynolds have been suspended before, The (Oklahoma City) Oklahoman reported Thursday. Reynolds was suspended for insensitive Twitter comments two years ago, and again last year for a rules violation. Franks, the team's leading kick returner, was suspended for two games last year for a rules violation.
The news that Sooner pass-catchers will be missing this season puts pressure on freshman Trey Metoyer, who received positive comments on his six-catch, 72-yard performance in the school's spring game, but the sudden lack of experience is a concern for a team who considered its passing game a strength, the newspaper said.
