Golden State Warriors shooting guard Klay Thompson developed "concussion-like symptoms" after Wednesday night's series-clinching Game 5 win over the Houston Rockets, the team announced.

Thompson left the game with a lacerated ear after being accidentally kneed in the head by the Rockets' Trevor Ariza in the fourth quarter. He was cleared to return but began not feeling well after the 104-90 win that lifted the Warriors to the NBA Finals, according to a statement released by the team.

"Klay Thompson was evaluated by the Warriors medical staff immediately after suffering an injury during tonight's game and was put through a concussion evaluation," the team said. "At the time he did not show any concussion-like symptoms. After the game he began to not feel well and developed concussion-like symptoms. He will continue to be evaluated by the team's medical staff tonight."

The Associated Press reported early Thursday that Thompson had suffered a concussion. However, the team and league haven't confirmed that Thompson did in fact suffer a concussion, and as such the NBA's concussion protocol isn't currently in effect.

Thompson said in a televised postgame interview that he was "feeling a little dizzy," before adding, "We got a week off -- or close to it. I'll be all right. I'll get my health back."

The injury occurred when Ariza, caught in the air on a shot fake, hit the right side of Thompson's head with his right knee. Ariza was called for a personal foul on the play.

Blood coming out of the cut prevented Thompson from checking back in to the game upon his return to the Warriors' bench. He ended up needing three stitches to close the wound.
