Miami Heat head coach Erik Spoelstra says swingman Justise Winslow has a concussion and entered the league's concussion protocol.

Winslow took a nasty hit from Denver Nuggets big man Paul Millsap. He missed the Heat's game on Thursday against the Phoenix Suns and obviously won't play on Friday versus the Los Angeles Lakers.

“Justise does have a concussion,” Spoelstra said, via Ira Winderman of the Sun-Sentinel. “He's going to go into the protocol.

“He didn't have really any symptoms until [Thursday]. And so we had him checked out by the Suns doctor and we'll find out more and he'll go through the protocol. We'll find out more when he goes through the protocol. He met with the doctor.”

Winslow is averaging 13.8 points, 8.0 rebounds and 4.8 assists on the season for the Heat. The lefty is shooting 38.9 percent from the field, 25.0 percent from beyond the arc and 58.8 percent from the free-throw line.

Miami is 6-2 on the season after defeating the Suns on Thursday. The matchup everyone will be paying attention to on Friday at Staples Center is Heat star Jimmy Butler versus Lakers superstar LeBron James.

The Heat will update the status of Winslow accordingly. In this situation, Winslow will only return once he's 100 percent.
