These are the breaks.

Ultimate Fighting Championship heavyweight champion, Randy Couture, successfully defended his belt Saturday at UFC 74. However, as his assistant revealed today, Couture suffered a broken bone in his left arm during the fight.

Randy CoutureCouture, 44, who defeated contender Gabriel Gonzaga by TKO in the third round, broke an ulna bone in his left forearm during the third round, said his assistant Valerie Haney.

“It happened on [Gonzaga's] high leg kick at Randy’s head,” Haney said. “Randy blocked the kick with his left arm.”

Couture, a five-time UFC champion in two weight classes, will have a splint on the arm for six weeks, a period that will extend into his plans to appear in a film being shot in South Africa.

The broken bone was discovered Sunday, Haney said. Couture was visiting a chiropractor in Las Vegas when he reported the arm was “sore, tender, swollen,” Haney said. An X-ray confirmed the break.
