Andy Webster will lead Hearts out against Motherwell on Saturday, manager Jim Jefferies has confirmed.
Webster, who captained Hearts in his first spell at Tynecastle, was handed the armband after Marius Zaliukas was sent off in the first half of the 2-2 derby draw at Hibernian on Sunday.
Jefferies said: "I think he's a natural successor to Marius if he's not available, so he'll lead the team out on Saturday in Marius' absence."
The Hearts boss expects goalkeeper Marian Kello to recover from a back spasm in time for the visit of Motherwell.
Adrian Mrowiec returns from suspension while Suso Santana (knee) and Eggert Jonsson (cheekbone) both hope to be available.
