Harlem Eubank would prefer his cousin, Chris Eubank Jr, to chase a legacy-defining fight against Saul 'Canelo' Alvarez rather than revisit his rivalry with Conor Benn.
The unbeaten welterweight says if Eubank Jr does fight Benn again, however, the weight discrepancy between the two Britons must be addressed.
Eubank Jr outpointed Benn in a grudge match at Tottenham Hotspur Stadium in April, more than two years after their original 2022 bout was cancelled due to Benn's failed drug tests.
A two-fight deal was in place, but Harlem is unsure whether a rematch will materialise.
"There's obviously a lot of money there for it, so potentially," he told BBC Sport.
"But Chris is 35 now and I'd like to see him take the Canelo fight and sail into the sunset.
"It's hard, because all the big opportunities come near the end of a career and there's always a fishhook dangling to keep you there, but I'd rather see him take the biggest fight in the sport and bow out."
