TORONTO -- Toronto Raptors rookie centre Jonas Valanciunas sustained a left calf strain during a voluntary workout over the weekend.
The Raptors said in a release Monday the injury isn't considered serious though there is not yet a timeline for his return.
The six-foot-11 Lithuanian was drafted fifth overall by the Raptors in the 2011 draft. He played with Lithuanian team Lietuvos Rytas last season, helping the club to a third-place finish in the second-tier Eurocup Basketball tournament and winning the competition's rising star award.
He is expected to be a key component of this season's new-look Raptors along with point guard Kyle Lowry, guard/forward Landry Fields and guard/forward Terrence Ross.
