Hearts interim boss Steven Naismith feels his side need to start carrying more of a threat if they are to bring their hopes of Europe back to life as he admitted an early injury to Michael Smith "doesn't look good."
The 1-0 loss to Hibs condemns Hearts to their sixth straight defeat - their first in the derby since Boxing Day 2019 - and marks a painful start to Naismith's run as interim manager who now sees his Jambos side remain five points behind Aberdeen in third.
A win for Aberdeen against Ross County piled on the pressure for Hearts who desperately needed to take something from their city rivals to prevent the slump in form, but Kevin Nisbet ensured the points would be staying in Leith.
