After being bothered by soreness in the leg through the first week of practice, Curry had an X-ray Friday that revealed the injury.
Georgia's Aug. 30 season-opening game at Clemson is three weeks away. If Curry is held out six weeks, he would miss three games — against Clemson, Middle Tennessee State and South Carolina — and could return just in time for the Sept. 20 game at Louisiana State.
Because Curry says he does not know when he suffered the injury, it was difficult for Georgia's medical staff to estimate how much time the senior will miss.
"What we don't know is if some healing already has started," Coach Mark
Richt said after Friday's practice. "Those stress fractures) are hard to detect."
Curry left the locker room Friday wearing an air cast that covered his foot and stopped below his knee.
"This is hurting me personally," Curry said.
"I have no idea when it happened. It has been bothering me all summer."
Georgia will have its first practice in full pads today, which also is the first day Georgia can have two practices.
Curry was named to the coaches' All-Southeastern Conference second team last season. Curry and free safety Sean Jones were expected to combine to give Georgia one of the strongest tandems at safety in the conference.
Sophomore Greg Blue likely will move up to the first-team defense at rover today. Blue played in every game as a backup last season and finished with 42 tackles. Redshirt freshman Olaolu Sanni-Osomo also could see more time as a top backup behind Blue and Jones — the role that had been forecast for Blue.
Curry led Georgia and tied for sixth in the SEC with four interceptions last season. He was rated the nation's fifth-best strong safety in a preseason ranking by The Sporting News. He was a preseason first-team All-SEC pick by Street and Smith's magazine and a second-team pick by SEC media last month in Birmingham.
Surgery planned for Jones: Georgia associate athletic director for ticket operations Freddy Jones is tentatively scheduled for quintuple heart bypass surgery Monday at Athens Regional Hospital.
Jones, 49, served as assistant sports editor of the Macon Telegraph for five years (1978-83) before joining the Georgia staff in 1983 as editor of the Georgia Bulldog Magazine.
Jones admitted himself to St. Mary's Hospital Wednesday morning after he experienced chest pains. He was transferred to Athens Regional. The bypass surgery originally was scheduled for Friday but was postponed after he developed a fever.
