All Black loose forward Liam Messam has taken many knocks in his rugby career but on December 3, he'll be taking some different knocks.
The 27-year-old is one of the rugby stars who singed up for this year's Woodstock Fight for Life - League versus Rugby.
Messam, who has nine test caps for the All Blacks, will step into the boxing ring for the first time.
"It's a totally different fitness. After my first sparring session, I have a lot of respect for what boxers do and how they train. It's a totally different sport, different fitness. Once you get fit it helps with the rugby fitness with the lungs and running and that," Messam said.
"It's been good, there's the whole other side that doesn't like to get hit but you've just got to get in there and get comfortable in the ring. Part of the sport is a contact sport, once you get comfortable hopefully it will go well."
