Golden State Warriors’ star Steph Curry suffered a left hamstring strain during Game 1 of the NBA Western Conference Semifinals against the Minnesota Timberwolves, raising major concerns for the rest of the series.

Fatigued Golden State players took Wednesday off after a physical 99-88 Game 1 victory over the Timberwolves, but coach Steve Kerr and his staff went to work determining how the Warriors will play on without superstar Stephen Curry for the next three games and possibly the rest of the best-of-seven series.

Curry and the defending champs had everything going their way heading into the playoffs. Curry scored 83 points in the final two games of the regular season, including 47 against Memphis as Golden State broke the 1996 Chicago Bulls’ NBA record with its 73rd win on the final day of the regular season.
