Derrick Lewis earned a knockout victory this past Saturday night but he also suffered a broken hand in the process.

Lewis finished Polish heavyweight Marcin Tybura with a jaw rattling knockout in the third round of their matchup this past weekend at UFC Fight Night in Austin, Texas.

Following the event, Lewis commented that his left hand was hurt and may have been broken and he confirmed that diagnosis on Wednesday via a post on Instagram.

“I have a 4th metacarpal fracture,” Lewis wrote alongside a rather painful looking video where the heavyweight contender is receiving some sort of injection into his hand.

The fourth metacarpal is just below the ring finger and a fracture will typically take between four to six weeks to heal before Lewis could be cleared to begin punching again. Recovery times are approximate and Lewis hasn’t disclosed yet how long the injury might keep him out of action.

The good news is Lewis did finish his fight by knockout, which puts him into position for a big matchup when he returns to action later this year.

Immediately following his win, Lewis mentioned that he would still like the chance to face former champion Fabricio Werdum after a back injury prevented him from facing the Brazilian last year. Lewis also showed interest in a potential showdown with ferocious heavyweight knockout artist Francis Ngannou, who just recently suffered a five round decision loss to champion Stipe Miocic.

Once his hand heals, Lewis will undoubtedly be anxious to book his next fight in 2018 as he hopes to earn a title shot before the end of this year.
