Junior middleweight Glen Tapia will face Salim Larbi instead of Boyd Melson, who suffered a torn rotator cuff injury during a sparring session on Tuesday, at New York’s Madison Square Garden on July 26, Tapia’s manager, Pat Lynch, informed RingTV.com. The bout will be on the undercard of a main event featuring Gennady Golovkin against Daniel Geale.

“I felt it stretch when I was throwing a punch and I immediately knew something wasn’t right. I tried to work through it but the pain only got worse,” said Melson. “First, my shoulder started to throb, then it got cold. Since I hurt my rotator cuff and had surgery twice in the past, I know what a tear feels like.”

Larbi (19-5-2, 7 knockouts), 27, of France, is 3-4 in his past seven fights and was last in action for a unanimous decision loss to Jack Culcay in April.

“I don’t like this last-minute stuff but what are you going to do?” said Lynch, whose fighter is trained by Freddie Roach. “Glen’s had a good, solid camp and he’s ready to fight. We did not want to ruin this opportunity to fight in front of all of these great fans at Madison Square Garden.”
