It sucks Mikey Garcia retired after his last fight. In his prime he was a pound for pound boxer

Shannon Briggs knocks Siarhei Liakhovich out of the ring with 1 second left in the 12th round of a fight he was losing on all 3 scorecards to win the WBO heavyweight world title.

Briggs was past his prime, asthmatic, and clearly gassed. Nobody would've been surprised if Briggs iced the guy early, but absolutely nobody thought he'd pull out a KO in the last second of the last round.
