ORIENT may still be waiting to play their weekend game, but it was a busy Saturday for their divisional rivals with eight League One games on the agenda.
Norwich City took advantage of Leeds United's FA Cup activity to knock the Elland Road club off top spot.
Leeds were busy drawing 2-2 at Premier League side Tottenham Hotspur and Norwich overcame Grant Holt's first half dismissal to beat Brentford 1-0 with Chris Martin's goal.
Colchester United were held to a 0-0 draw by struggling Gillingham, who moved ahead of the O's with their point.
It was a good weekend for Milton Keynes Dons, who moved level on points with sixth-placed Huddersfield Town thanks to Jason Puncheon's decisive goal in a 1-0 victory over Tranmere Rovers.
Neil Harris' 51st minute penalty gave Millwall a single-goal success at relegation-threatened Oldham Athletic.
Bristol Rovers maintained their unlikely play-off push with a 2-0 win over Hartlepool United. Chris Lines and Darryl Duffy were the men on target for the Pirates.
Yeovil Town bounced back from their midweek defeat to the O's by beating Exeter City 2-1 and moving up to 12th in the table. Stefan Stam gave the Glovers an early lead, and although Adam Stansfield levelled for the Grecians, Ryan Mason's 41st minute goal handed Yeovil the points.
Two goals in four second half minutes meant the points were shared between Southend United and Wycombe Wanderers. Alan McCormack fired the Shrimpers into the lead, but Josh Payne levelled for the Chairboys, and 1-1 was how it finished.
Stockport County arrested a run of 12 successive League defeats with a 0-0 draw at Carlisle United. Former O's man Jabo Ibehre was dismissed for the Hatters late on, but they held on to their point.
