Carl Froch has apologised for threatening to "kill" Mikkel Kessler in their IBF super-middleweight fight in London on Saturday night – but will still face an investigation by the British Boxing Board of Control.

Froch wrote on Twitter: "I'm sorry if my comments offended anyone. This fight means so much to me & emotions are running high. See you at the weigh-in."

The Board's general secretary Robert Smith said the governing body would look into the commentssaying: "Carl's comments are inappropriate and we are disappointed in them."
