ATLANTA — The NCAA upheld its four-game suspension of Georgia tailback Todd Gurley on Thursday night, ending the school's final hope of having its biggest star in uniform for Saturday's game against Florida. In a statement released Thursday night, the NCAA's student-athlete reinstatement committee denied Georgia's appeal of Gurley's four-game suspension. The NCAA announced the suspension on Wednesday, when it said Gurley accepted more than $3,000 for autographed memorabilia and other items over a two-year period.
