Leyton Orient chairman Barry Hearn says he would be interested in a possible ground share of the Olympic Stadium with West Ham United.
criticised the Hammers' plans
to move from Upton Park in the past.
But he told BBC Sport: "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.
"We will now talk with the Olympic authorities."
The League One side's chairman had previously considered moving to the Olympic Stadium, but withdrew on the basis that it was "not fit for football".
Hearn feared that if West Ham moved away from Upton Park it could
threaten the O's survival by tempting fans away from Brisbane Road.
The newly-promoted Premier League club have been looking at the feasibility of including retractable seating at the venue, which is due to be converted into a 60,000-seater stadium after the Games.
In March the
Hammers were named as one of four bidders looking to take control of the stadium
following the conclusion of the Games.
At the same time it was confirmed that the O's were not among the quartet.
If the ground share were to be successful, it would be the first time two London clubs have shared a home ground on a permanent basis.
The London Legacy Development Corporation has extended the tenancy bidding process until after the Games.
