UFC veteran Diego Sanchez has gone under the knife once again, this time to repair a broken collarbone.

Sanchez (25-7 MMA, 14-7 UFC) sustained the injury during training on Monday and today announced he had successful surgery to repair the damage. MMAjunkie confirmed the news with manager Ricky Kottenstette, who said Sanchez should only be sidelined four to six weeks before he can resume training.

Depending on the severity of the break, a collarbone injury can take anywhere from four to 12 weeks to heal completely, according to MedlinePlus. Sanchez’s damage was on the lesser side, Kottenstette said.

Sanchez was not officially confirmed for a fight at the time of the injury and has been out of action since June 2014, when he took an extremely controversial split decision over Ross Pearson at UFC Fight Night 42.

The 33-year-old was expected to face Joe Lauzon at UFC 180 in November. However, shortly after Lauzon announced an injury would keep him from the fight, Sanchez revealed a knee injury of his own would prevent him from participating at the Mexico City event.

Sanchez is just 2-3 in his past five trips to the octagon, with his wins over Pearson and Takanori Gomi coming by debated split decision. He losses came to Myles Jury, Gilbert Melendez and Jake Ellenberger.

“The Dream” can add the broken collarbone to the growing list of injuries he’s sustained since his 2005 UFC debut. He’s graced the octagon 21 times in his career, but during that stretch, he’s dealt with staph infection, a broken hand and repeated knee issues.

Despite the latest setback, Kottenstette said his client’s spirits are high and he’s confident he’ll soon be preparing for his next bout.
