As a former All Blacks first-five and current head coach of South African franchise the Eastern Province Kings, Carlos Spencer is used to tough challenges, but getting in the ring with experienced boxer Monty Betham on Saturday night is among his biggest yet.
The pair, who showed off their impressive physiques when posing topless for the cameras in Auckland today ahead of their professional Fight for Life bout at the Claudelands Arena, will both carry some anxiety into the ring, however.
Spencer has some boxing experience - he has fought in two previous Fight for Life events with a draw against Awen Guttenbeil in 2011, and a victory over Jarrod McCracken a year later, but never against someone of Betham's quality.
"It's a personal challenge," Spencer, who arrived in New Zealand on Monday, said. "When Duco got in touch with me I didn't think I would put the gloves on again. Time isn't on my side, but I thought why not give it a shot. For me it's a one-off opportunity, they don't come around that often."
Betham, too, will feel the pressure. He has fought professionally six times, including against Shane Cameron in 2011 over six two-minute rounds, a bout in which he held his own but lost on points.
