Mavericks suspend Delonte West

The Dallas Mavericks suspended guard Delonte West for conduct detrimental to the team, coach Rick Carlisle told reporters.

Though Carlisle didn't cite a reason, ESPNDallas.com reported that the punishment stems from a locker room outburst following the Mavericks' preseason win Monday.

He tweeted late Monday: "Sorry moma..." and "I showed off on ur birthday again..."

An eight-year veteran, West has been diagnosed with bipolar disorder. That condition contributed to a September 2009 arrest on weapons charges, an incident that led a 10-game suspension by the NBA league.

West averaged 9.6 points and 3.2 assists last season for the Mavs.
