Burns, 30, endured a clean break from the second round of the fight, which most thought Beltran did enough to win, although the judges carded as split decision draw to allow the Scot to retain his WBO lightweight belt.
Hearn was ringside as always to witness the fight and praised a dogged Burns for his bravery in fighting on to complete the fight in agony, with the injury clearly visible throughout the contest.
Beltran has already spoken of a rematch, possibly in America, but Hearn dismissed any talk of a second fight yet after spending the night with Burns in hospital and admitted he has fears over Burns’ career.
“I can’t guarantee that (a rematch),” Hearn told Sky Sports News. “I can’t even guarantee that Ricky Burns will even box again.
“Ricky will have a titanium plate put in his jaw and we just don’t know how he is going to recover from that. It’s a major operation and obviously the jaw is a major part of a boxer’s make-up.
“Beltran is a lovely guy. I spoke to him at length after the fight. I think that is a fight that would appeal to people.
“Ricky has a defence due, probably against Terence Crawford, but really right now after seeing him last night is hospital my main concern is for Ricky Burns’ health. His career comes second. My gut feeling is that he will come back but it will be at some time that he is ready to fight again.”
