The American shocked James DeGale on UK soil back in December, proving an awkward customer for the former Olympic gold medallist.
Ahead of the rematch next month, Truax has promised to make the result even more one-sided when DeGale heads across the Atlantic to Nevada on April 7.
“They made the right call on the decision in England, and I expect to be even more dominant this time around,” Truax said.
“I am planning to really just beat up James Gale and get the job done in more efficient fashion this time.
“Fighting in Las Vegas for the first time will be a very cool experience and I expect it to be friendlier than it was in London.
“There is a lot of pride on the line for me, being that I’m the first boxing world champion from Minnesota in a long time.
“So there is a lot on the line for me and I plan to keep that going, especially as a means for supporting my family.”
Opponent DeGale admitted he was below par but refrained from taking anything away from the man who inflicted his second career loss.
“I’m happy to have the opportunity to rematch Truax and regain my IBF title,” said DeGale.
“I am not going to make excuses for my poor performance, actions speak louder than words. I am excited to be boxing in Vegas and on SHOWTIME again.
“The real JD will be back on fight night!”
