West Ham United appear to have edged into the lead in the race to win the Olympic Stadium after the games.
The Premier League side are competing against rivals Tottenham Hotspur for the right to move to the property after the closing ceremony in 2012.
A decision is expected following a meeting of the Olympic Park Legacy Company executive committee tomorrow, however, reports suggest West Ham have won the endorsement.
If confirmed, the decision would represent a victory for athletics in the UK.
West Ham have consented to maintain a running track in the Olympic Stadium, despite concerns this would dilute the atmosphere at football matches.
The team also face relegation from the Premium League, casting doubt over the financial viability of the scheme.
Tottenham, in contrast, had outlined plans to demolish the existing structure, replacing it with a stadium designed exclusively for football.
The club do, however, have planning permission to build a 56,000-seat stadium on the site of their present ground at White Heart Lane.
