Mark Cuban is personally helping Delonte West get back on his feet ... with the Dallas Mavericks owner picking up the ex-NBA star at a gas station in Texas.
As we previously reported, the former Cleveland Cavaliers guard has fallen on tough times in recent years ... and was most recently seen holding a sign on the street in Dallas last week.
Sources connected to West's family tell us that Cuban -- who had been trying to reach DW on the phone for days -- finally got in contact with Delonte ... who agreed to meet the Mavs owner on Monday in Dallas.
