ATHENS, Ga. – Georgia coach Mark Richt got a bit testy when asked if he expects suspended running back Todd Gurley to play against Arkansas.

Richt said on a conference call Sunday that he knows nothing about the timetable for the school's investigation into possible violations of NCAA rules. When pressed on the issue, he said "we might just end this thing."

But Richt finished out the call, saying he's hopeful that injured running back Keith Marshall may return against the Razorbacks. Another injured back, freshman Sony Michel, could be back for a Nov. 1 game against Florida.

Gurley, in the meantime, is suspended indefinitely.

Even without the Heisman contender, Georgia blew out Missouri 34-0 behind Nick Chubb's 143 yards rushing. The victory propelled the Bulldogs to No. 10 in the AP poll.
