The Memphis Grizzlies today announced that forward Darrell Arthur sustained a small, non-displaced fracture in the head of the fibula in his left leg during a recent workout while preparing for training camp.

The injury was diagnosed by team physician Dr. Fred Azar after Arthur underwent a magnetic resonance imaging (MRI) at the Campbell Clinic earlier this week.

The 24-year-old is being treated by the team’s athletic training staff and will be evaluated on a weekly basis by Dr. Azar.  He will return to action in an estimated 4-6 weeks but could return earlier if symptom-free.

In other news, center Hamed Haddadi will return to full action without any restrictions after an eight-week rehabilitation following right thumb surgery.
