Golden State Warriors star Kevin Durant will have his strained right calf reevaluated on Thursday and will miss at least Tuesday’s Game 1 of the Western Conference finals against the Portland Trail Blazers, a source told ESPN’s Ramona Shelburne.

It’s unlikely Durant will play in Thursday’s Game 2, according to the source.

Durant injured his calf in the third quarter of Wednesday night’s 104-99 Game 5 win over the Rockets in the conference semifinals.

With 2:11 left in the quarter, Durant went up for a jumper over Rockets swingman Iman Shumpert and landed awkwardly. Initially, Warriors personnel were concerned that Durant had suffered an Achilles injury, but an MRI on Thursday confirmed the calf strain.
