This shows it more clearly, it's pretty obvious it hits his finger. I thought it was a try before seeing this and I'm English!

Still not seeing it, there is no obvious movement to indicate contact and that camera angle isn't helping as the hand appears behind the ball with no depth to give perspective, could just be a reaction your seeing thinking he might catch it as that's what he was trying to do, the whole thing was accidental, not intentional.
