BARCELONA, Spain — Lionel Messi was substituted after suffering what Barcelona coach Luis Enrique called a "slight pain" during halftime of Barcelona's 6-0 rout of 10-man Athletic Bilbao on Sunday.
Messi showed no signs of being slowed down as he helped Barcelona build a 2-0 lead after opening the scoring with a penalty in the seventh minute.
Luis Enrique replaced the Argentina playmaker with Arda Turan at halftime, saying later that he had done so as a precaution.
He said Messi "will have the necessary tests, but he has a slight pain. We preferred not to take a risk."
Barcelona club president Josep Bartomeu had said earlier that Messi "doesn't have anything wrong."
In September, Messi tore a ligament in his left knee and was sidelined for two months.
