Nuneaton Town manager Brian Reid has left the Conference club after only five months in charge.
Boro are now looking for their fourth manager since March after calling time on Reid's spell at Liberty Way.
The 43-year-old Scot signed a one-year contract taking him up to May 2015 when he took over from caretaker boss Mark Noon, who was in charge for a month after Kevin Wilkin's move to Wrexham.
Noon has again taken temporary control of the Conference strugglers.
Assisted by Nicky Eaden and James Ellis, a club statement has confirmed that he will be in charge for Tuesday night's home game against high-flying Forest Green.
|Kevin Wilkin: June 2006-March 2014|
|Mark Noon (caretaker): March-April 2014|
|Brian Reid: April-September 2014|
|Mark Noon/Nicky Eaden/James Ellis (caretaker): September 2014|
"It's a decision taken by the board which we believe is the right thing to do," Boro chief executive Ian Neale told BBC Coventry & Warwickshire. "An agreement was made by all parties it could not continue in that way.
"Certainly there were some issues. But I don't think it would be right for the club or Brian to discuss personal matters. We've got to agree a deal with Brian over the settlement of his contract."
Reid only took charge of 10 Boro matches, having taken over in April from Noon, after a run of just one point from five matches following Wilkin's exit..
After losing their first game under Reid, they then finished last season unbeaten in their final two matches - and have struggled since last season's top scorer Louis Moult departed to join his old boss Wilkin at Wrexham.
"You could say it's my mistake," added Neale. "I appointed Brian, so I want to put it right."
