Defender Mohamadou Sissoko should return from a groin injury for Kilmarnock as they entertain Hearts.But midfielder Craig Bryson is a doubt, while Mehdi Taouil, Frazer Wright and Ryan O'Leary miss out through injury. [LNB]Hearts winger Suso Santana is out for the season after undergoing knee surgery and Ismael Bouzid is suspended. [LNB]Captain Marius Zaliukas returns from a ban, but Andy Webster, Ruben Palazuelos, Andrew Driver and Rudi Skacel are all fitness doubts. [LNB][LNB]Kilmarnock caretaker manager Kenny Shiels: "We have had four centre-halves missing. We have had to reshuffle, playing a full-back at centre-half and a player who hadn't played for 11 months. [LNB]"We have patched up the back four. I don't think we have the depth to cover. [LNB]"If it happens to Rangers and Celtic, they can do it, but we have no underbelly. [LNB]"That has had a major influence on these goals conceded. When a team concedes four and four again, it can breed negativity, but we are preparing positively - the response has been good in training." [LNB]Hearts manager Jim Jefferies (on the aim to wrap up third place): "It would be ideal if we could get it tied up. [LNB]"We're in a great position and we know that win has been elusive for the last few weeks, but we've been picking up points. [LNB]"The most important thing for us is to go to Kilmarnock and get a result. [LNB]"Even though they've beaten us twice at home and had a great season, we managed to get a result against them down there. [LNB]"We'll keep our fingers crossed we can do it again."
