Shane Mosley has some friendly advice for Dana White -- DON'T ACCEPT OSCAR DE LA HOYA'S BOXING CHALLENGE ... fight him in the Octagon instead!
Remember, Oscar and Dana have been beefing hard lately -- with Dana calling Oscar all sorts of nasty names on ESPN.
So, Oscar issued a challenge of his own -- going on Sirius XM's Luke Thomas show and saying, "Let's get in the ring. Three rounds. Let's do this."
In a fight between @OscarDeLaHoya and @danawhite, who you got?
