Dillian Whyte edged out American heavyweight Jermaine Franklin on a majority decision after their 12-round contest at Wembley Arena.
Whyte was returning from defeat to Tyson Fury in April at neighbouring Wembley Stadium and had a battle on his hands against Franklin, with one judge, Michael Alexander scoring their bout level at 115-115.
The other two judges, Juergen Landos and Grzegorz Molenda however both scored the fight 116-112 for Whyte.
Searching for a way past Franklin, 34-year-old Whyte started getting frustrated but landed a gigantic right hook that rocked the American.
The pair traded shots in the last round and Whyte connected with another right to put Franklin on the ropes before the bell signalled the end.
While a former rival, and former world champion, Anthony Joshua was ringside to watch Whyte and could be viewing him as a potential opponent for 2023.
