Sky Blues fans have already voiced their displeasure at the deal which will see their League One fixtures will take place 34 miles away from the city, at the home of the Cobblers.
The situation arose because of a long-running rent dispute between the owners of the Ricoh Arena and the football club and Malcolm Clarke, chair of the Football Supporters' Federation, feels for the long-suffering supporters.
"This is a terrible day for Coventry City and its supporters," he said. "To see your club ripped from the community from where it was born must be one of the hardest things a fan can go through.
"Football is not a normal business, clubs are woven into the fabric of their area's history. The game's governing bodies should act earlier to stop things ever going this far.
"It's quite clear to the FSF that clubs shouldn't move without gaining approval from fans first. No Coventry City fans that we've spoken to back this move."
