Leyton Orient chairman Barry Hearn has said that he would be open to the idea of a ground share of the Olympic Stadium with West Ham United.
Hearn has previously criticised the Hammers' pursuit of the stadium, labelling their bid to secure the 60,000-seat arena as "fundamentally flawed" because it did not receive the backing of the Football League.
The O's chairman now appears willing to negotiate.
"Subject to the changes West Ham are asking for, namely covering the running track, we'd be interested in bidding for the stadium as part of a ground share with them," Hearn told BBC Sport.
"We will now talk with the Olympic authorities."
Hearn and Orient's main fear of West Ham moving away from Upton Park is that it could threaten the O's survival by tempting fans away from Brisbane Road.
Tottenham Hotspur were also previously interested in moving into the Olympic Stadium.
