The original date was Tuesday, 9th March, when West Ham are now at home to the Dons, and so the fixture against Nottingham Forest has been put back 24 hours to the same venue, kick off at 7 o'clock.
Jobi McAnuff, who sampled the Upton Park atmosphere for the recent FA cup game against Fulham sitting with fellow former Don Adam Nowland in his executive box, will be one of three players signed from Wimbledon this season - the other being Nigel Reo-Coker, of course, and he says:
"It is nice to be at a club where the fans come out in such numbers."
But he warns that Wimbledon will be no pushover, and explains:
"At Wimbledon we always tended to do well when there were bigger crowds, away from home."
Alan Pardew is keen that there is no complacency amongst fans or players ahead of the game and says:
"It is absolutely essential the fans don't sit on their seats and wait for us to turn them over.
"We need that intimidating atmosphere and we want the support to be even more vocal to see us home."
As for Jobi's own situation, he says:
"I am still getting into it here to an extent, and feeling positive."
