Mtolo became
captain of Richards Bay and helped the team win the
2021-22 National First Division and thus promotion to the
2022-23 South African Premier Division. He missed the start of that season because of a knee injury requiring surgery. Despite prospects of return being in February 2023, Mtolo surpassed expectations and made his Premier Division debut in December 2022 as a substitute. On 7 March, Mtolo collapsed during the team's training session. It was an ordinary training with 15 minutes left. When assisted by teammates and the club's physiotherapist, Mtolo struggled to breathe. He was rushed towards a hospital in a private car belonging to Richards Bay's general manager, but died underway. ==Personal life==
