I don’t think you can be surprised by anything that Delonte West does. His mental issues are well documented and when he is off his meds he is prone to doing odd things.
Details are scarce but according to Larry Brown Sports, Delonte had a bit of an outburst in the locker room after the Mavericks preseason game against Rockets.
How long the suspension will be and how it effects Delonte’s status on the team has yet to be determined.
