Draymond Green has suffered an injury "setback" forcing him out of a second straight game, according to Golden State Warriors head coach Steve Kerr.

Kerr revealed Green's right knee contusion had "flared up", meaning he was a late scratch for Sunday's game against the Minnesota Timberwolves.

The four-time NBA All-Star had missed Friday's 116-101 win over the Houston Rockets due to the same injury.

"It flared up today," Kerr told reporters pre-game. "He will be more thoroughly checked today by our medical staff.

"It was sort of unexpected, the way he came through treatment yesterday, everything was looking good. He had a setback today, so we'll learn more today and we'll have more for you tomorrow."

Kerr confirmed it was likely Green, who is averaging 7.4 rebounds and 6.8 assists this season, would undergo an MRI on the injury.

The reigning NBA champions are already without two-time NBA MVP Stephen Curry due to a leg injury.
