Gervonta Davis says his next match against Shakur Stevenson will be his final bout in boxing. The proposed bout has Stevenson publicly calling it the end of Davis' career. Multiple boxing sources confirm Davis plans to retire after the fight. Roy Jones Jr. now argues Davis must push hard against Stevenson to prevail and secure a clean exit from the sport. The fight, if it happens, would cap Davis' run as a five-division world champion.
