Athens, Ga. ? Freshman Joe Cox may have won more than a game with his fourth-quarter performance Saturday.

Cox rescued No. 9 Georgia, throwing two touchdown passes in the last 9:11 – the second a 20-yarder with 46 seconds left – and the Bulldogs came back to beat winless Colorado, 14-13.

With Georgia now heading into its Southeastern Conference schedule next week at Mississippi, Cox may have earned his first start.

“It’s hard to say exactly what to do for sure,” said Georgia coach Mark Richt, who already has tried Joe Tereshinski and another freshman, Matthew Stafford, as starting quarterbacks.

Now, the quarterback competition is open again.

“We’ll have to step back and look at the big picture again, but Joe Cox threw his hat in there real strong,” Richt said.

Cox, who took over late in the third quarter for an ineffective Stafford, threw a 23-yard TD pass to fullback Brannan Southerland for Georgia’s first touchdown. Cox capped the comeback with his 20-yarder to tight end Martrez Milner.

Colorado, 0-4 under new coach Dan Hawkins, built a 13-0 lead behind quarterback Bernard Jackson, who passed for 140 yards and ran for 85 yards and a touchdown. But Cox brought the Bulldogs (4-0) back from the brink of what would have been a shocking loss.
