As if going into an Edinburgh derby after sacking your manager following five straight defeats that relinquished third place was not bad enough, Hearts now find themselves even further behind after Aberdeen's Friday night win in Dingwall.
Less than two years after switching from playing to coaching, former Scotland striker Steven Naismith has been put in charge until at least the summer and has already shown he can take tough decisions by showing veteran midfielder and former international team-mate Robert Snodgrass the exit door.
An equally quick change of fortunes is required at Easter Road is needed to keep ajar Hearts' chances of third - and the same could be said of hosts who themselves have lost four in a row.
Only two days after manager Lee Johnson insisted his side could still finish third, Hibs now find themselves 10 points behind the Dons - and, with Livingston only a point behind, could yet be denied a top-six finish.

FT: Ross County 0-1 Aberdeen
Aberdeen took a firm grip on third place in the Premiership after last night's 1-0 win away to Ross County.
A sixth straight win under caretaker Barry Robson means they are now five points clear of a Hearts side who go into today's Edinburgh derby under their own interim boss, Steven Naismith, for the first time after Robbie Neilson's Sunday exit.
