Around 12 photographers were on the beach in Malibu Saturday afternoon trying to get shots of Matty hitting the surf, when an all-out smackdown was laid on the pappers by turf-protecting surfers.
One pap was hit in the face and we're told suffered a broken nose, while another was thrown into some rocks and had his camera smashed. McConaughey was not involved in the ruckus.
Police tell us a battery report was filed by one photographer but no arrests have been made.
A rep for Matthew has yet to get back to us.
