SAN FRANCISCO -- Golden State Warriors star forward Draymond Green has been ruled out of Monday's home game against the Boston Celtics with a left calf strain, while Stephen Curry is questionable with a left ankle sprain.

Head coach Steve Kerr said Green was supposed to undergo an MRI on Sunday, and the Warriors are expected to give an update on his injury Monday.

The Warriors could be looking at some time without their defensive leader, who limped off the floor just three minutes into Saturday's game with the calf injury and was ruled out shortly after that.

Green had just returned after missing the three previous games due to illness and a back issue.

Curry, meanwhile, injured his left ankle near the end of Saturday's 122-114 win over the Washington Wizards. He said Saturday in the locker room that he "feels great" and "see you on Monday."

The Warriors (21-20) have been hit hard by injuries. Jonathan Kuminga injured his right ankle on Jan. 4 and was ruled out for at least three weeks. He likely will need longer than that to return. Brandin Podziemski has been out since Dec. 28 with an abdominal injury. Kyle Anderson is out with a glute injury.
