Beni Baningime and Calem Nieuwenhof remain unavailable as they continue their return from injury.
The Heart of Midlothian midfield duo have not played this season.
Nieuwenhof has been out since suffering a hamstring injury in the win over Celtic back in March. Baningime has been absent since sustaining an issue around his knee.
Steven Naismith revealed Baningime has returned to training but Nieuwenhof is still building up to joining him.
"Beni has been back in training but he's not close to being considered for matches," he said.
"Calem is a wee bit behind him, he's still doing individual stuff on the grass but he's on the grass. Calem is the one we want to make sure he is right so he doesn't break down."
Meanwhile, James Penrice will return to the Hearts squad for the Europa League play-off clash with Viktoria Plzen having sat out of the Motherwell loss.
The club will give Lawrence Shankland as long as possible before deciding if he is fit enough to face the Czechs at Tynecastle Park.
