New Zealand heavyweight David Tua says he has shaken off a calf muscle injury and is ready to fight against Belarusian Alexander Ustinov next month.
Tua is confident the bout in Hamilton on November 16 will see him at his lightest fighting weight since tipping the scales at 107kg ahead of his win over compatriot Shane Cameron in 2009.
He says his calf injury was simply down to overworking his old legs.
"I've been training pretty hard and I was doing some exercise stuff that I wasn't used to in the past, the old legs got tired and they went pop," Tua says.
"There is still a bit of work to be done. I can't get too relaxed. The key now is to stay focused."
Tua says it's been hard to control his eating over the past few months and is adamant he hasn't 'fallen off the wagon' once.
"It's been hard because I'm Samoan and I love my food!"
40-year-old Tua boasts a professional career record of 52 wins from 58 fights, including 43 knockouts.
There have been two draws and four losses, which includes his last fight, more than two years ago when Barrett won a unanimous points decision in Auckland.
The 2m tall Ustinov, 36, has lost just once in 29 fights and has knocked out 21 opponents.
