The Heisman Trophy and college football playoff races received a possible jolt Thursday when Georgia announced star running back Todd Gurley had been suspended indefinitely while the school investigates a possible violation of NCAA rules.
"I am obviously very disappointed," Georgia Coach Mark Richt said in a statement. "The important thing for our team is to turn all our attention toward preparation for Missouri."
No. 13 Georgia (4-1) plays at No. 23 Missouri (4-1) in a key Southeastern Conference East game that comes with playoff implications.
Gurley ranks fourth in Football Bowl Subdivision rushing with 773 yards and eight touchdowns. He is averaging 8.2 yards a carry.
Gurley overtook Oregon quarterback Marcus Mariota this week in a survey of Heisman Trophy voters by USA Today.
A source told ESPN the investigation centers on whether Gurley was given money for autographs and memorabilia.
Former Texas A&M quarterback Johnny Manziel was suspended for the first half against Rice last year as he faced similar accusations. Manziel was cleared of wrongdoing and played out the season.
The news was yet another hit for the SEC. On Monday, Florida announced it had suspended quarterback Treon Harris indefinitely as a result of a sexual assault allegation.
