Assistant coach Ruben Uria, who will lead the team for the top-of-table clash, said Valencia are taking it one game at a time.
"We will try to win any way we can and close the distance with Barca," Uria said.
"At this stage of the season, it is hard to say we're going to fight for the title."
Murillo will have tests on Monday with Valencia fearing he has torn a muscle in his groin.
"They were better than us in the first half but we got back into it in the second half," Santi Mina said.
"We have shown that we can win playing well and playing not so well."
