Messi admits he had concerns when first breaking down.
"It was nothing more than a knock," he told Marca.
"I couldn't see what it was properly in the picture, whether it was broken or not. Luckily it was just a knock. Many things have been said.
"I've heard that the club and I were hiding things. I did not hide anything. I'm coming back from an injury, it was tough because I relapsed and that made me more careful and recover better."
