The Golden State Warriors are rolling. On Saturday night, they extended their winning streak to seven games with a 97-94 victory over the New York Knicks — moving to 15-1 with Jimmy Butler in the active lineup.

Golden State Warriors guard Stephen Curry is questionable to play Monday against the Denver Nuggets at Chase Center, according to the NBA’s injury report. Curry is nursing a right lower back strain. He’s played Golden State’s last 21 games.

For the game, they could be without their best player, as two-time MVP Steph Curry is on the injury report. Curry is averaging 24.0 points, 4.4 rebounds, 6.2 assists and 1.1 steals per contest while shooting 44.
