Legendary musician today ... the next Don King tomorrow?!?!
It sure sounds like Usher is considering that route ... 'cause when we got him out at Avery Sparrow's pre-Ryan Garcia fight event -- he told us he's dead serious about possibly getting in the boxing business!
"I'm obviously here for a reason," Usher says ... "Who knows? I may be bitten by the bug."
Usher's had some history with the sport ... he famously played Sugar Ray Leonard in "Hands of Stone" back in 2016 -- and he's close with Sparrow and his boxing family.
