The Golden State Warriors are already down one of their stars. Now they await word on their biggest one.

Twelve-time All-Star guard Stephen Curry, the greatest shooter of all-time, walked off the floor Wednesday, Nov. 11 during a game against the Houston Rockets, clearly grimacing. Curry, who appeared to be favoring his right side, then walked to the locker room, with a trainer following. The Warriors announced minutes into the second quarter that Curry would not return for the rest of the game with right abdominal soreness.

The sequence took place just 5:35 into the game. Curry had scored 3 points on 1-of-3 shooting by that point. Curry did not return to the floor for the rest of the first quarter, and he was not back at the bench area to start the second period.

Curry did have a collision with Rockets forward Amen Thompson earlier in the game, when Curry had driven to the hoop on an attempted layup. Then, Curry had been fighting off a screen against Rockets center Alperen Şengün. As soon as that sequence ended, Curry once again grabbed his side.

Finally, just moments before he left the game, Curry curled around a screen and put up a 3-point shot. As soon as he landed and stepped backwards, he grabbed at his right side, near his hip.

Curry has been in the midst of a renaissance and has been elevating the play of the Warriors, who entered the night 8-3, which was tied for the third best record in the Western Conference.

Curry has been averaging 30.6 points, 4.1 rebounds and 4.3 assists per game across nine appearances so far this season. He’s converting 3-pointers at a blistering 45.7%, which would mark a career-high. His scoring total ranks second in the NBA, behind only Luka Dončić’s historic 39.3 points per game, for all players with at least five games played.
