Oregon star freshman Bol Bol's college career is over, he announced Thursday.

Bol has been sidelined for the past four games because of a left foot injury and is unlikely to fully recover before the end of the season.

Bol's attorney, Bryan J. Freedman, released a statement saying Bol underwent surgery Thursday to repair a non-displaced fracture of the navicular bone in his left foot. Bol will begin rehab next week, Freedman said, and will use crutches or a boot for eight to 10 weeks before returning to basketball activities in the summer.

"Bol had been treating this injury wearing a walking boot for the past few weeks and although his foot pain completely resolved, repeated imaging studies revealed that the fracture was healing very slowly," the statement said. "At surgery, 2 screws were inserted into the navicluar bone and bone graft from his pelvis was added to speed up the healing which will expedite his return to play."

The 7-foot-2 center is ranked No. 5 in ESPN's NBA draft rankings, slotting in as the No. 1 center in the class.

A former top-five recruit, Bol had been a dominant force during his nine healthy games in Eugene. He was averaging 21 points, 9.6 rebounds and 2.7 blocks. He logged four double-doubles -- including a 32-point, 11-rebound performance in a loss to Texas Southern in late November.

Bol also was shooting 52 percent from 3-point range, an attribute that intrigues NBA executives because of his size.

Oregon (9-4) is off to a slower-than-expected start this season and will now move forward without the possibility of Bol returning. Freshman Francis Okoro has seen a boost in playing time since Bol's injury, while the return to health of freshman Louis King has added another dimension to Oregon's frontcourt.

The Ducks open Pac-12 play on Saturday at home against Oregon State.
