Dual weight world champion Timothy Bradley has announced his retirement from boxing.
Bradley, 33, had not fought since April 2016, when he suffered only his second career loss, both of which came at the hands of Manny Pacquiao.
He retires with a 33-2-1 record, 13 of those wins coming via knockout, and held the WBC and WBO light welterweight titles before moving up to welterweight and claiming the WBO belt in that division in the first of three clashes with Pacquiao.
Bradley made his retirement announcement while commentating on Vasyl Lomachenko's WBO super featherweight title defence against Miguel Marriaga in Los Angeles.
And he later said on Instagram: "To you, the diehard fans, man, it's been one heck of a ride.
"The bumps, the bruises, the peaks, the valleys, the days I didn't want to get out of bed and the nights I couldn't sleep….So many occasions where my heart, mind and soul were tested but with every challenge there was hope and there was all of you…giving me the courage to fight another day and do what I loved to do.
"I can never find the words to convey how much I appreciate all of you and how truly humbled I am by the unconditional support the past 23 years, thank you.
"Thank you for cheering me on when I didn't deserve it, loving me most when I needed it and for being my heartbeat to keep going day after day. I am the man I am today because of you all."
