Viktoria Plzen will come to Tynecastle Park for the second leg of the Europa League play-off fresh from a weekend off.
Heart of Midlothian's opponents have had their league match postponed due to their involvement in the European play-offs. Plzen were due to face Sigma Olomouc on Sunday evening at the Doosan Arena.
The Czechs bring a 1-0 lead to Gorgie after Daniel Oyegoke's unfortunate own goal in stoppage time handed the home side the victory.
"Yes, I am very glad for this decision," Plzen boss Miroslav Koubek said. "I am very glad the Czech football association supports the teams playing in Europe so we save some energy, especially for the midfield players who are very active in how they play. It is a very good decision and I'm glad for this."
In Plzen's league match between their second leg against Kryvbas and Hearts first leg, they made six changes ahead of the visit of Steven Naismith's men.
Hearts will travel to Fir Park to face Motherwell on Sunday looking for their first win of the season.
