As previously reported on BoxingScene.com, Joseph Parker's team says the WBO heavyweight champion is at ''maximum speed and power'' ahead of his unification fight against Anthony Joshua.
Parker underwent elbow surgery in November in his native New Zealand to deal with ''pain and restriction'' in both arms.
His team says ''the results of the surgery have been nothing less than fantastic with Parker regaining maximum speed and power for the first time since 2016.''
The surgeon who operated on Parker, Craig Ball, says the surgery has given Parker a greater range of motion and taken away pain.
Parker is hoping to take Joshua's WBA, IBF and IBO belts in the fight on March 31 in Cardiff. The fight will be carried by Showtime in the United States and Sky Sports Box Office in the UK.
While Parker (24-0, 18 KOs) is a big underdog in the fight, WBC heavyweight champion Deontay Wilder recently explained that he has a legit shot at victory.
"He has a 100 percent chance of winning. He has to be smart and stick to the game plan," Wilder said.
"In this ring it's not about how much a person weighs, or about how big a person's muscles is - it's about heart, that dog that he's going to bring to the fight. The mind is powerful ... speak it, believe it, receive it."
Speaking to Trackside Radio, Parker's trainer Kevin Barry said Wilder has meant a lot to the 26-year-old WBO champion.
"We have a relationship with Deontay. We were sending him messages during the week, he actually sent a couple of messages to us," Barry told Trackside Radio.
"He wants to hang with us in Cardiff so there is good mutual respect there. He is an experienced guy and he knows it is all about following a game plan and it was good for us to hear him say that."
