Middlewieight boxer Sherif Lawal has passed away after collapsing in the ring following a knockout punch in his professional debut in the UK.
He was only 29 years old.
Lawal's first pro fight went down Sunday at the Harrow Leisure Centre in London ... where he faced Portuguese fighter Malam Varela (2-4).
During the 4th round of the Clash of the Titans undercard fight, Varela threw a right that landed directly on Lawal's temple, knocking him to the ground ... and the referee could tell Sherif needed immediate medical attention.
