This is GREAT to see -- Delonte Westlooking happy and physically active at his rehab center!!
Mark Cubanshared some pics of the ex-NBA star as he continues his treatment ... which now includes frisbee golf and kayaking!
Cuban, who was the driving force behind getting 37-year-old West into treatment, commented ... "Because we all want something to feel great about today, here is your Delonte West update."
He added, "It's still an uphill battle, but he is climbing."
As we previously reported, Cuban personally picked up West at a Dallas gas station last month and vowed to help out in any way he could after seeing pics of Delonte in late-September in bad shape, begging for money on the streets.
