Draymond Green is doubtful to play against the Denver Nuggets on Tuesday due to left calf soreness.
"We got to be careful. We will see how he holds up," said Steve Kerr on Monday.
Green has appeared in all 19 games for the Warriors this season.
Steph Curry, who is experiencing knee pain, is listed as probable.
"This is what it's going to be for our team at this point, and Draymond and Steph's respective careers. So we've got to try to keep their minutes down as best we can. We've got to try to keep them healthy by being proactive," added Kerr.
