Memphis Grizzlies forward Darrell Arthur has suffered a fractured left fibula during a recent workout, the team announced Wednesday.
Team doctors said Arthur, 24, is expected to be out 4-6 weeks. That mean he could miss most of training camp, which opens next week.
The fourth-year player from Kansas missed all of last season with a torn Achilles' tendon. He has averaged 10.1 points and 4.9 rebounds in 17 career games.
