The NBA has suspended Memphis Grizzlies guard Matt Barnes two games for a physical altercation with New York Knicks coach Derek Fisher at the home of Barnes' estranged wife in Southern California in October, league sources told Yahoo Sports.

Fisher had flown to Los Angeles on an off day of Knicks training camp and was visiting with Barnes' estranged wife, Gloria Govan, with Barnes' children at the house.

Barnes, 35, confronted Fisher and a physical altercation ensued. Barnes and Fisher had been good friends as teammates with the Los Angeles Lakers.

Barnes is expected to serve the suspension in Tuesday's game against the Miami Heat and Saturday's game at the Utah Jazz. He will lose about $64,000 in salary because of the suspension.

Barnes has averaged 8.5 points for the Grizzlies this season.
