Barcelona coach Ernesto Valverde says an injury to Leo Messi isn't serious.
Messi scored twice for their 2-2 draw with Valencia, though pulled up with a thigh injury.
"Between tomorrow and the day afterwards we'll need to see exactly how he is and what he has," Valverde said.
"I don't exactly what it is.
"It could be a small discomfort.
"We'll wait to see what the doctors say, then evaluate things based on that.
"I imagine that he can't be too bad, but I'm not able to reveal anything."
