Former Strikeforce champion Alistair Overeem was shocked recently when he left the Octagon following a loss to Ben Rothwell.

Overeem believed he had Rothwell right where he wanted him after landing a kick that sounded as if the heavyweight had suffered a broken arm. Instead, Rothwell landed a shot and dropped “The Reem,” sending him to his third UFC loss.

“I was in a great shape and prep was superb,” Overeem wrote on Instagram. “About the fight – I made a mistake. Hearing Ben’s arm crack on one of the kicks I didn’t expect him to counterpunch with the same arm.

“We knew Ben is a tough strong guy, well we got it confirmed.”

The 34-year-old Overeem (37-14) has now lost three of his last four, including knockouts against Travis Browne and Antonio Silva. He did earn a decision win over Frank Mir this past February for his first victory since 2011.

While some have questioned if Overeem will continue fighting, he doesn’t appear ready to transition away from the sport.

“Now today, new day – new chances,” he wrote. “It might not always go as we want or as planned but….As long as we have freedom and high spirits we are/should be OK. This coming from myself who’ve had several downturns in both life and career but plenty of great moments in life to so not complaining.

“Big Ben was a little to much this time, looking ahead and forward to the next challenge.”
