The Canaries have lost four of their last six games - including Saturday's 1-0 loss to West Brom - to leave them five points off the drop zone with just five games remaining.
The Canaries are currently 17th in the Premier League, five points off the drop zone with just five games remaining although the club has lost four of their last six games, including Saturday's 1-0 home defeat to West Brom.
"Norwich City can confirm Chris Hughton, Colin Calderwood and Paul Trollope have parted company with the club with immediate effect - and former Canary winger and FA Youth Cup-winning coach Neil Adams has been appointed as First Team Manager," a statement on the club's website read. "The Norwich City Board has taken the decision to give the club the maximum chance to secure the points required between now and the end of the season to ensure retention of our Barclays Premier League status."
Adams, who played for the club for more than six years and most recently has coached the Under-18 side said he is thrilled to be taking on the job.
"To say that I am delighted to have been offered the opportunity of managing Norwich City Football Club would be a massive understatement," he said. "People know what this club means to me, and so it goes without saying that we will be doing everything possible to ensure that we maintain our top-flight status for next season.
"These final five games will be a huge test for us, and everyone must step up to the mark. But with the full backing of these magnificent Norwich supporters we will have every chance of achieving our objective."
