Oscar Molina's pro debut on hold

The pro debut of two-time Mexican Olympian Oscar Molina is on hold.

Molina, a welterweight who competed in the 2008 and 2012 Olympics, was scheduled to turn pro on Saturday in Ciudad Juarez, Mexico, but has been sidelined with an injury, according to promoter Dan Goossen.

"He had pain in his left shoulder a few weeks back that didn't get any better and was restricting him from using his left arm," Goossen told ESPN.com. "After a doctor's visit, he was told to get an MRI and it showed a cyst on his left shoulder pressing against the nerve, which was causing the problem. The doctor drained the cyst [Wednesday] and told Oscar the cyst should not be a problem in the future. He'll be off for 2-3 weeks."

The 22-year-old Molina, who lives in Norwalk, Calif., is the twin brother of 2008 U.S. Olympian Javier Molina (11-1, 5 KOs), who is also promoted by Goossen and scheduled to fight on Saturday's card. Their older brother is lightweight Carlos Molina (17-0-1, 7 KOs), who is moving up in weight to face former junior welterweight titlist Amir Khan on Dec. 15 in Los Angeles.
