“The Road Warrior” won’t retire anytime soon.

Glen Johnson will turn 43 in two months and is 2-3 over the last two years. He hopes, however, to prove that he’s still capable of beating elite-level opponents, beginning Saturday night in Quebec City against unbeaten IBF super middleweight champ Lucian Bute (Showtime; 9 p.m. EDT; 6 p.m. PDT).

“I have plans on going on and moving forward,” Johnson said. “I feel great. I look to put on a tremendous performance [against Bute]. I expect to come out of the fight victorious. For me, it doesn’t have anything to do with age. I feel great and I’m just looking forward to putting on a great fight.”

His age isn’t the only remarkable number concerning Johnson (51-15-2, 35 KOs). The Jamaican-born, Miami-based boxer is extremely rare in that he actually has been able to move down in weight at an advanced age.

The former undisputed light heavyweight champ left the 175-pound division a little over a year ago to participate in Showtime’s “Super Six World Boxing Classic,” a super middleweight tournament.

“I have no problems making the weight,” Johnson said. “The weight is not an issue. We’ve made the weight the same way when we came to this class. We’ve made it fairly easy and it’s getting easier each time, so weight is not an issue.

Johnson is 1-1 in that division, though his last 168-pound fight wasn’t nearly as competitive as most of his fights.

Despite that judge Nobuaki Uratani somehow scored their 12-round fight even (114-114), England’s Carl Froch decisively defeated Johnson to retain his WBC super middleweight crown June 4 in Atlantic City. The scorecards of judges Mark Green (116-112) and John Stewart (117-111) were much more reflective of the action in the ring that night.

When asked how he performed against Froch (28-1, 20 KOs), who advanced to the “Super Six” final against Andre Ward (24-0, 13 KOs), Johnson said, “Poorly. I was very disappointed in what I was doing. It was a close fight and it was an exciting fight, and I know I have plenty more in me than what I showed him.”
