The Golden State Warriors may be without centre Andrew Bogut for the immediate future after the NBA championship winner was diagnosed with a concussion.

Bogut will need to be cleared under the NBA's concussion protocol before he can play again, the Warriors announced on Wednesday.

The Australia left Tuesday's season-opening 111-95 win over the New Orleans Pelicans after being struck in the head in the third quarter.

Bogut had scored 12 points, five rebounds, five assists and two blocked shots in just over two quarters. 

The Warriors play two games on the road, at the Houston Rockets on Friday and the Pelicans on Saturday.
