Diamond Dallas Page -- Don't Give Up On Scott Hall ... 'Recovery Is a Process'

Wrestling legend Diamond Dallas Page says he knows his friend Scott Hall has "stumbled" in his ongoing battle with substance abuse ... but says he still has Hall's back -- no matter what.

Page has essentially been a sober mentor for both Hall and Jake "The Snake" Roberts -- who both had serious issues with alcohol and drugs after becoming world famous wrestling stars.

Now, with Hall being escorted out of a wrestling event in NJ this weekend for allegedly showing up drunk, Page says he wants Hall to know he can count on him for support.

"Scott is going through a life process. He's stumbled along the way, but he is doing well over all. I've got his back."

Page adds, "Even Jake 'The Snake' has fallen a few times, but he is now one year sober and doing great."

DDP says he plans to speak with Hall soon ... and hopes he can help get Hall back on the sober path, asap.
