Philadelphia 76ers owner Joshua Harris is on the verge of pulling out of a potential deal to buy Charlton Football Club, according to the Daily Mail.
American businessman Harris, who also owns NHL ice hockey side the New Jersey Devils, was reportedly keen on buying the south London side.
Harris was said to be willing to pay the £43million current co-owners Tony Jimenez and Michael Slater are looking to sell the Championship club for.
However reports suggest Harris has had second thoughts about buying the Addicks, which will come as a major blow to Charlton.
Charlton, who are currently languishing just above the relegation zone, have yet to offer manager Chris Powell and several of his players new deals, as the current owners were waiting to see if Harris wanted to put his own stamp on the team.
Powell's current contract runs out at the end of the season, which means Charlton co-owners Jimenez and Slater will have to either offer the former Addicks defender a new deal or find another potential suitor to buy the former Premier League side.
