JJB Sports has been approached by a 'number of non-binding indications' of interest for its chain of health and fitness clubs.
The group's share price soared by up to 70 per cent yesterday following reports that the chain could be sold for £55m.
However, JJB Sport said: "There can be no certainty that any of these indications of interest will result in a transaction or as to the terms of any such transaction. A further announcement will be made when appropriate."
Bidders, reportedly, include JJB founder David Whelan, Sports Direct founder Mike Ashley, and Fitness First, the world's largest fitness club operator.
The firms also announced today that its fashion chains, Qube and the Original Shoe Company, have been placed into administration after failing to find a buyer. KPMG have been appointed as the administrators.
