Adrien Broner thinks Maxim Dadashev's death from in-ring injuries was tragic ... but the star boxer tells TMZ Sports nothing about the sport has to change going forward.
"Hell nah," Broner says ... "Ain't nothing got to change."
Dadashev -- a 28-year-old Russian junior welterweight contender -- took repeated punches to the face and head during his fight last Friday night with Puerto Rico’s Subriel Matias.
After his trainer threw in the towel to stop the bout ... Dadashev collapsed and was rushed to the hospital -- where he later died Tuesday from brain injuries suffered during the fight.
