DraftKings also told The Post that it is “aware of potential concerns” about the fight.

Duljaryan, 29, lost by submission, but commentators Daniel Cormier and Michael Chiesa were confused as to what was happening, calling Del Valle’s finish “white belt stuff”, thinking it wasn’t the most complicated stuff.
What makes Dulgaryan’s stance even more interesting are his comments about his belief that fighters should get a share of the bets on matches.
