The Foxes take on Blackpool in a Third Round replay this evening, and should they win through to the fourth round and then draw with Reading away from home, the replay will take place on the date originally scheduled for the visit to Portman Road.
International matches are scheduled for the week starting 7th February and as a consequence the Football League and Premiership have agreed to play the replays on February 12th. The Town match will then be re-arranged for later in the season.
Should that happen, it's likely that Town's next home game will not be until 22nd February when Watford visit Portman Road, meaning over a month would pass inbetween the last home match and the next one.
