Carl Froch vs. George Groves II, billed as Unfinished Business and The Rematch, was a professional boxing match contested on 31 May 2014 at Wembley Stadium in London.

The result was heavily protested by Groves and his team, as well as by fans and the media, creating immediate demand for a rematch.

[4][5] The rematch was officially announced on 4 March 2014 by Matchroom Boxing promoter Eddie Hearn,[6] for whom Froch had fought since 2011[7] and Groves since 2013.

As with their first fight, Froch and Groves appeared on Sky Sports' boxing magazine show Ringside.

[12][13] In the build-up to the rematch there was much animosity between both boxers, with copious amounts of trash-talk and each vowing to score a knockout.

[14][15] The weigh-in took place on 30 May at the nearby Wembley Arena, in front of 4,000 raucous fans who were predominantly in support of native Londoner Groves.

"[16] As part of the entrance spectacle, Groves first entered the arena on an open top bus, accompanied by the song "Underdog" by Kasabian.

Froch, who entered to a medley of "We Will Rock You" by Queen and "Shoot to Thrill" by AC/DC, chose a more conventional walk through the stands.

Round five was action-packed, as several exchanges of clean punches from both boxers elicited a standing ovation from the crowd.

In the sixth, Froch pressed forward while landing more punches, but Groves responded with his own at the end of the round.

Without any controversy this time, referee Charlie Fitch immediately waved off the fight as a knockout at 2 minutes and 43 seconds, as Groves attempted to stand up on shaky legs.

"[21] In the following days, he went on to express satisfaction in having soundly beaten his rival: "I've had to endure some serious abuse, silly games and unnecessary antagonising.

"[23] On 14 September, Groves returned to the ring and scored a unanimous decision against Christopher Rebrassé, winning the European and WBC Silver super-middleweight titles.

[24] After announcing his retirement, he spoke more fondly of the event and rivalry with Groves: "We all did ourselves proud and you couldn't have written the script for what happened.

"[26] The attendance figure of 80,000 stood as a British post-War record until being surpassed by Anthony Joshua vs. Wladimir Klitschko in 2017, which drew 90,000.
