Carlisle have sacked boss Greg Abbott after a poor start to the League One season. The Cumbrians have taken just two points from their first six matches and lost 1-0 to Port Vale on Saturday.
The 49-year-old was the third longest-serving manager in English football, having taken charge late in 2008.
"Unfortunately the continued dip in attendances, in direct relation to results, left all parties with no other option than to reach this conclusion," said a club statement.
