Thompson received stitches in his right ear and passed a concussion test during the game that would have allowed him to return. The Warriors did not need him as they won the game 104-90 to clinch the series.
The Warriors said Thompson developed concussion symptoms after the game and will be evaluated by the medical staff. Thompson must pass the concussion protocol before he can return to play.
The Warriors will face the Cleveland Cavaliers in the finals starting on June 4 only on ABC7. Game 1 will be on Thursday, June 4 starting at 5:30 p.m. PT.
