Anthony Crolla's promoter Eddie Hearn will fight to get the British lightweight a rematch after his majority points draw with Darleys Perez on Saturday.
Crolla (29-4-3, 11 KOs) was left bemused and disappointed at scores of 113-113, 113-113 and 116-111 that meant Colombian Perez (32-1-1, 20 KOs) kept his WBA word lightweight title at Manchester Arena. MC Michael Buffer announced the wrong scores after the fight - he announced scores of 113-113, 116-111 to Crolla and 114-113 to Perez - and Hearn also insists two of three judges got it wrong.
Hearn claimed he had already contacted the WBA governing body at a press conference less than an hour after the fight to complain about the decision.
"I'm gutted, sickened for Anthony and I thought he won by four rounds," Hearn said. "I can't see why he's not world champion.
"We will be asking for an immediate rematch and I will pay him [Perez] to come here if I have to because I know I can fill the arena with Anthony Crolla.
"I've emailed the WBA complaining about the points decision and asking for an immediate rematch. If there were two points deducted how could they have given the fight to Perez by two rounds? No way."
Crolla, 28, thought he had had done enough to earn the decision after containing Perez with his jab and neat boxing through the fight. There were close rounds but Perez became increasingly frustrated at being unable to land any hurtful combinations.
"With the two-point deduction I thought I had definitely done enough to get the decision and I'm devastated," Crolla said.
"At the same time I'm a very lucky man and I'm thankful for the opportunity to fight for a world title in front of my own fans and to get a reception like that. It was almost a dream come true."
Crolla's first world title fight came just seven months after he had been hospitalised by a brutal street attack by two burglars he had chased off from a neighbours house. Crolla was left with a fractured skull and a broken ankle in two places.
Crolla thought Perez's low blows were a testament to how his boxing had left the WBC champion frustrated.
"That was the plan, to frustrate him," Crolla said. "I think it went to plan, we tried to make him over reach and miss and he was frustrated by my jab.
"I dug as deep as I could, I gave it everything and it's made me more determined to come back and try again."
