FROM RAP TO THE RING
Tekashi 6ix9ine has been spending a ton of time in the boxing gym recently ... but those looking to see him settle his many beefs in the ring are SOL -- 'cause TMZ Sports is told the rapper is NOT interested in taking a celebrity fight.
The New York rapper hit up the Black Box gym in Dubai earlier this week ... getting in a workout with 17-3 Iranian boxer Mohammad Ali Bayat Farid.
You can see the 26-year-old look throwing a couple of right hooks at Farid's mitts and working some defensive moves .
