The Dallas Mavericks say center Dereck Lively II has a stress fracture in his right ankle and will be re-evaluated in a month.

The Dallas Morning News spoke to Kenneth Jung, a foot and ankle surgeon at Cedars-Sinai Orthopedics in Los Angeles, to gain insight into Lively’s stress fracture, treatment and recovery timetable. Jung’s education includes a 2005 fellowship in foot and ankle surgery at Baylor University Medical Center in Dallas.
