SAN ANTONIO — Spurs restricted free agent swingman Kyle Anderson has signed a four-year, $37.2 million offer sheet with the Memphis Grizzlies, league sources confirmed.

The Spurs have until Sunday to match, but sources say they are unlikely to do so.

With All-Star Kawhi Leonard sidelined for all but nine games with a quadriceps injury, Anderson started 67 games while averaging career bests in points (7.9), rebounds (5.4), assists (2.7) and steals (1.6).

The Grizzlies have promised Anderson a role to his liking, the sources said.

Anderson is a favorite of Spurs coach Gregg Popovich, who in praising the UCLA product frequently cited his versatility.

“He is like a utility infielder in baseball,” Popovich said. “He can do a little bit of everything, and he sets an example. He’s worked into this role.”

Anderson, who turns 25 on Sept. 20, was selected in the first round by the Spurs in 2014 as the 30th overall pick.
