While Thompson did manage to come back and finish the game, he was seen limping afterwards per Rusty Simmons of The San Francisco Chronicle.

The Warriors have already clinched a post-season berth so rushing Thompson back is unnecessary. With plenty of depth, head coach Steve Kerr views Thompson's minor injury as an opportunity for other guys to step up. He is considering starting Justin Holiday in the backcourt. According to ESPN's Ethan Sherwood Strauss :
Kerr said he saw some benefit in losing his star for a stretch, saying, "It's not a bad thing. We get playing time for Justin [Holiday] and [Leandro Barbosa] and play Shaun [Livingston] a little bit more, play Harrison [Barnes] in that spot.
We are all familiar with Stephen Curry's ankle history. Hopefully, Thompson's injury is a minor issue and he will be fully healthy for the playoffs and a title run.
