Carl Froch left Tony Bellew stunned when he claimed Amir Khan was "only good for getting knocked out".
Khan was suggested as a possible opponent for Conor Benn after joining the young star in the ring following his second-round KO of Chris Van Heerden on Saturday night. Khan shied away from the challenge as he considers whether to fight on after being stopped by Kell Brook in February.
Bellew and Froch were discussing potential opponents for Benn after his 21st professional victory when Froch said: "I like the Kell Brook fight. You mentioned the Amir Khan fight but he's only good for getting knocked out that kid; he needs to retire now. Amir Khan needs to turn it in. I'm just being straight, I'm being brutally honest."
