Heart of Midlothian have sacked Head Coach Steven Naismith and his assistants Gordon Forrest and Frankie McAvoy.
The capital club are on a run of eight successive defeats in all competitions and sit bottom of the William Hill Premiership table after Saturday's 2-1 loss to St. Mirren.
Naismith replaced Robbie Neilson at Tynecastle and led the club to a third place finish in the top flight last season.
Hearts gained one point with a 0-0 draw with Rangers on the opening day of the 2024/25 league season but have since lost five league matches, exited the Premier Sports Cup to William Hill Championship side Falkirk and dropped into the UEFA Conference League after defeat to Viktoria Plzen.
After bringing the coaching team's 17-month tenure to an end, Hearts chief executive Andrew McKinlay told the club's website: "Results and performances have fallen below the standards expected at this football club and, unfortunately, there is little evidence of any potential upturn in fortunes.
"With our UEFA Conference League campaign about to commence, and the spotlight on our league position, we cannot afford to stand still. That is why we, as a Board of Directors, have made the difficult decision to part ways with the management team, who go with our thanks and best wishes."
