Torn Achilles’ tendon ends Mario Chalmers’ run with the Grizzlies

Grizzlies guard Mario Chalmers will miss the rest of the season after rupturing his right Achilles’ tendon, and Memphis waived the veteran to clear up a much-needed spot on the roster.

The Grizzlies announced both the severity of Chalmers’ injury and the roster move Thursday night.

General Manager Chris Wallace said in a statement that Chalmers has been an important part of the Grizzlies’ success this season. But Chalmers’ injury is season-ending, and the Grizzlies have so many injuries already Wallace says they had to free up a roster spot.

Chalmers was hurt with 6:57 left in the third quarter Wednesday night in Boston with the Grizzlies down 64-61 in what wound up a 116-96 loss. He was taken out of the locker room in a wheelchair.

Bosh did not offer any potential timetables for his return. ...

The Sacramento Kings have suspended center DeMarcus Cousins for one game for “conduct detrimental to the team.” While the Kings offered no other details about Cousins’ conduct, video from Sacramento’s 120-111 home loss to the Cleveland Cavaliers on Wednesday showed Cousins sitting on the bench and in the huddle yelling and heatedly gesturing with his arm at Coach George Karl, who was only a couple of feet away.
