Stevenage have announced the departure of manager Gary Smith.
Stevenage have dropped to 15th in League One after a dismal run of 14 defeats in their last 18 games, and Tuesday's 2-0 loss to Bury proved the final straw.
Captain Mark Roberts has been placed in temporary charge, having previously acted as caretaker last year.
Chairman Phil Wallace told the club's official website: "It's always difficult when you have to replace the man in charge. Gary has done his best but the performances and results over the past few months have been worrying in the extreme.
"After a very promising start with a new squad, we have slipped alarmingly and the board are concerned that the present management team may be unable to deliver the club's vision of increasing attendances and developing players in a winning environment.
"We have waited longer than most others in similar circumstances, but we cannot in all good conscience continue to watch this downward spiral and do nothing.
"It's time for a change and we'll see who applies for the position. Meanwhile I'm indebted to skipper Mark Roberts who will, once again, step up and take charge whilst our search takes place."
