Fields took two months off from workouts to rest his foot after last season ended. After playing in a summer league with other Pitt players, he said he felt some slight pain in his foot. Instead of resting it more, Fields had the surgery, hoping it would end the problem for good. Pitt basketball spokesman Greg Hotchkiss said the surgery was successful, and Fields is expected to rehab for about eight weeks. He added that Fields, who is currently on crutches, will have the cast off his foot shortly and isn’t expected to miss any games. Pitt begins practice Oct. 17.
