Marius Zaliukas is suspended for Hearts as they host Motherwell after he was sent off in Sunday's Edinburgh derby.Rudi Skacel, Suso and Eggert Jonsson are doubtful, while Lee Wallace, Kevin Kyle and Calum Elliot remain out. [LNB]Motherwell's Stevie Hammell has an outside chance of making the bench and boss Stuart McCall will make late decisions on some unnamed players. [LNB]Francis Jeffers, Gavin Gunning and Steve Jennings are definitely out through injury. [LNB][LNB]Hearts midfielder Ryan Stevenson: "It looked so easy at one stage that we were definitely going to get third spot in the league. [LNB]"When you open up that big a gap, you maybe switch off and think we're 12, 15 points in front, we're fine - but the gap closes very, very quickly. [LNB]"We know that if we go off the boil Dundee United will be right on our tails. [LNB]"For us personally we've got to take it every game at a time." [LNB]Motherwell manager Stuart McCall:"It's a tough one at Hearts tomorrow, but we'll be going there and want to pick up something. [LNB]"We'll go and play in the same spirit as we have done recently and hopefully come back with something. [LNB]"If we got a point it wouldn't be the worst result in the world but wherever we go we look to get the three. [LNB]"If we came away with a point or three it would be a terrific result."
