Scunthorpe have announced manager Neil Cox has parted company with the club.
The Iron are currently rock-bottom of Sky Bet League Two having won only two and lost eight of their 15 league games this season.
Scunthorpe finished 22nd last term - three points clear of the relegation zone - after appointing Cox in August 2020.
Saturday's 2-1 loss at Colchester proved to be the final game of the 50-year-old's tenure.
A statement on the club's official website on Monday read: "Scunthorpe United has parted company with first-team manager Neil Cox and assistant manager Mark Lillis.
"We thank them both for their efforts while with the club.

"Coach Tony McMahon and goalkeeping coach Paul Musselwhite will take charge of the team for the FA Cup first-round game against Doncaster Rovers this weekend."
Speaking after what proved to be his final game in charge, Cox said: "We will get them in tomorrow, look at the video to reflect on how we started the game and we go from there.
"There is no point in me ranting or raving at them now because I feel angry at the moment so instead of me 'going off on one' we will get them in tomorrow and will have a look at the game."
Cox's exit means the Iron are searching for what will be a 15th appointment in the last 11 years.

Nigel Adkins was in the hotseat for four successful years until 2010, when he left for Southampton. And since then it has been a revolving door at Glanford Park.
Men to have taken charge since are Ian Baraclough, Alan Knill, Brian Laws (second spell in charge), Russ Wilcox, Andy Dawson, Mark Robins, Nick Daws, Graham Alexander, Daws (again), Dawson (again), Stuart McCall, Dawson (a third time), Paul Hurst and then Cox.
The early betting market has Adkins as favourite for a return to his old club, with Keith Hill and Michael Flynn also featuring prominently.
