Warriors guard Brandon Williams will undergo an MRI after suffering a left hamstring injury during Monday’s thrashing of the Pelicans, according to head coach Steve Kerr (Twitter video link via Kenzo Fukuda of ClutchPoints).

Kerr said Williams’ injury is a “big concern,” particularly in the context of Will Richard tearing the ulnar collateral ligament in his left thumb, per Fukuda.

“He’s a huge part of our team, and he’s given us such a lift,” Kerr said of Williams. “And it’s a hamstring. He’s going to get an MRI, so we’ll see how bad it is.”

Williams sustained the hamstring injury in the first quarter of Monday’s game, which the Warriors went on to win by a staggering 51 points. In his eight healthy outings this season, the 26-year-old has averaged 11.1 points, 2.6 assists, 2.3 rebounds and 1.0 steal in 17.8 minutes per game.

A free agent addition over the summer, Williams signed a minimum-salary contract with Golden State. His deal is currently partially guaranteed for $1.4MM.
