Lucas Matthysse is off the May 7 HBO Pay-Per-View card headlined by Canelo Alvarez and Amir Khan because of further discomfort in his injured left eye, Golden Boy VP Eric Gomez told RingTV.com on Wednesday.

Matthysse (37-4, 34 knockouts) was in training to face Mauricio Herrera in the May 7 co-feature at T-Mobile Arena in Las Vegas but felt recurring pain in his left eye, which was originally injured in his Oct. 3 junior welterweight title fight with Viktor Postol. Matthysse refused to rise off the canvas in the 10^th round of that fight because of what he described as temporary blindness. He later had fluid drained to alleviate pain. Though the welterweight clash between Matthysse and Herrera wasn’t finalized, they were both far along in negotiations.

Golden Boy is now targeting the fall for Matthysse’s comeback bout. There are no thoughts that he will retire, Gomez said. “Lucas didn’t want to go through with the fight because he didn’t feel 100 percent,” Gomez said in a phone interview. “He was in camp and felt discomfort in his eye. It’s a scary thing when you feel pain in your eye still. He doesn’t want to go blind. So after meeting with his doctors a decision was made for him not to go through with his fight. He’s going to rest for a couple of months and then come back in the fall.”

Gomez said he is meeting with Golden Boy president Oscar De La Hoya on Wednesday afternoon to explore alternatives for the undercard, such as whether to keep Herrera on the show against another opponent.
