MEMPHIS, Tenn. -- The Memphis Grizzlies' injury list keeps growing longer with wing Ziaire Williams out for at least the rest of March and guard Derrick Rose sidelined a minimum of three weeks.

The Grizzlies announced Tuesday that Williams has a Grade 2 strain of a hip flexor and his lower back. Williams was hurt in an overtime loss Saturday night to Portland. He will be re-evaluated in four weeks, less than two weeks before Memphis concludes this season April 14.

Rose left the second quarter of a loss last week at Minnesota with soreness in his groin and low back. He has been diagnosed with right osteitis pubis and will be re-evaluated in three weeks.

Memphis had used 35 different starting lineups and 20 different starters going into Monday night's game at Brooklyn. The Grizzlies snapped a five-game skid with a road win Monday night despite missing Jaren Jackson Jr. and Yuta Watanabe with injuries.

The Grizzlies have had starters like two-time All-Star Ja Morant, Desmond Bane and Marcus Smart sidelined for weeks by injuries.

Memphis (21-41) currently has the third-worst record in the Western Conference and sixth-worst in the NBA.
