Hearts manager Paulo Sergio has warned the nine players walking a suspension tightrope to focus only Sunday's William Hill Scottish Cup semi-final with Celtic.
Captain Marius Zaliukas, Rudi Skacel, Andrew Driver, Darren Barr, Danny Grainger, Scott Robinson, David Templeton, Suso Santana and Jordan Morton are all in danger of being suspended for the final should they pick up a second yellow card of the competition at Hampden on Sunday.
But Sergio will demand his players hold nothing back, and said: "If they're going to be careful because of a yellow card, maybe they can't play at 100% and if we don't play at 100%, we're not going to be in the final."
He added: "If I have one or two doing that and we win the game and go to the final, maybe they don't play the final, even if they don't pick up a yellow card.
"I'm not saying I want them to get a yellow card, but every single day when you go to do your job you have to give 100%."
Sergio says Hearts' task is tougher after Celtic were beaten 1-0 by Kilmarnock in the Scottish Communities League Cup final last month. Celtic last week sealed the SPL title with a 6-0 defeat of Killie.
The Portuguese boss added: "I believe that defeat Celtic had is going to make our semi-final even harder.
"They already lost one cup and I'm sure they're going to be even more alert so that doesn't happen twice.
"They are favourites. We're going to be the first team to play against them as champions. They have had a fantastic season. They deserve this title. We know they are favourites. They have a fantastic squad, with a fantastic manager.
"We know it's going to be tough for us, but, like I've said before, maybe if we play 10 times against Celtic we can win one or two - I hope Sunday will be one of those."
