Margarito was outclassed by Pacquiao
Antonio Margarito is scheduled to have eye surgery on Tuesday after his bruising defeat by Manny Pacquiao.
"Margarito has a fractured right orbital bone," said a spokesman for fight promoter Bob Arum.
"After the fight was over, he had some stitchwork done in the locker room. They put six stitches in his right cheek and three through his eyebrow."
Mexican Margarito lost the WBC super welterweight title fight to Pacquiao by an unanimous points decision.
Despite weighing 17 pounds lighter than Margarito, Filipino Pacquiao outclassed his opponent over 12 rounds at the Cowboys Stadium in Dallas on Saturday to claim an eighth world title in an unprecedented eighth weight class.
"I truly, truly think the job of the trainer is to protect your fighter and Margarito's corner should have saved him," said Pacquiao's experienced trainer Freddie Roach. "He [Margarito] may never fight again.
"He took too much unnecessary punishment to me. I would have stopped that fight. After eight rounds, it was over and it was just a matter of time."
Margarito's procedure will be carried out at Dallas Methodist Hospital, according to organisers.
