Michael Bisping has retired from MMA, calling time on a stellar career in which he became the UK’s first UFC champion. Having dealt with complications with his right eye since 2013, Bisping revealed that he suffered a separate injury to his left eye following the Gastelum fight. “The Count” said he started seeing “flashes” out of his left eye at a party in the aftermath of his loss to Gastelum, and those issues have persisted in the months since.
