*Carl Froch's Nottingham homecoming might have to be moved to an outdoor venue because of "relentless" interest from fans. *

He returns to the ring after December's defeat by Andre Ward in the Super Six tournament final.
Froch will get the chance to regain his world champion status when he meets unbeaten IBF holder Lucian Bute on May 26.
