Motherwell have parted company with manager Ian Baraclough in the wake of Tuesday's League Cup defeat against Morton at Cappielow.
The 44-year-old former Sligo Rovers boss had been in charge since December 2014, when he replaced Stuart McCall, and he kept the Fir Park side in the top flight following a two-legged play-off victory against Rangers in May.
Motherwell are currently 10th in the Ladbrokes Premiership, with seven points from eight games, and face bottom club Partick Thistle on Saturday.
A club statement issued on Wednesday read: "The Board of Directors would like to sincerely thank Ian for his great efforts last season and keeping the club in the SPFL Premiership for this very important season - with the 130th anniversary and the 25th anniversary of the 1991 Scottish Cup celebrated at the end of the season.
"The Board will immediately commence the search for a new manager. In the interim, current Under 20s boss Stephen Craigan, along with Stephen Robinson (assistant manager) and Jim Hollman (goalkeeping coach), will handle first-team affairs."
