Fabricio Werdum isn’t letting his latest setback keep him down.

The former heavyweight champion was knocked out for just the third time in his 32-fight career on Saturday, succumbing to strikes at the hands of Alexander Volkov in the fourth round of the main event of UFC London.

Werdum wrote that he was grateful for his supporters, and though he is disappointed in the loss, he is keeping a positive attitude:

“I am fortunate to have happiness and determination in my heart and to be surrounded by people who respect me and who give me the energy that I need to continue my path of success.

“Thanks for the support and know that each one of you is very important to me!”

Werdum, 40, is now 3-3 in his last six fights. After losing to Alistair Overeem by majority decision at UFC 213 last October, he bounced back with consecutive victories over Walt Harris and Marcin Tybura before falling to Volkov in London.
