Three-time super middleweight titleholder Carl Froch has officially retired from professional boxing. Promotional outfit Matchroom confirmed the news via a press release in the early morning hours Tuesday (U.K. Time).

Froch (33-2, 24 knockouts) brings down the curtain on an illustrious career which saw him compete against the very best at 168 pounds. Since December 2008, “The Cobra” has bested Jean Pascal, Jermain Taylor, Andre Dirrell, Arthur Abraham, Lucian Bute, Mikkel Kessler and George Groves.

His final fight, a rematch against Groves in May of last year, was contested in front of 80,000 fans at Wembley Stadium in London and set a post-World War II attendance record. The dramatic eighth-round-stoppage was punctuated by a brutal right hand, which will likely be remembered as the finest punch the Nottingham man every landed.

Froch had climbed onto many pound-for-pound lists the past few years.

“I’m incredibly proud of what I have achieved in boxing but now is the right moment to hang up my gloves,” Froch said. “I have nothing left to prove and my legacy speaks for itself.”

The 38-year-old had dangled a carrot in front of fans over the last couple of months, claiming that a showdown with the fearsome Gennady Golovkin was possible. He never sounded certain, however, and has expressed contentment ever since his final triumph.

The former champion will now join Adam Smith, Johnny Nelson and other expert analysts as part of the Sky Sports boxing team in the U.K.
