A spectator is carrying the scars of watching Colin Montgomerie lose his lead at the Volvo PGA Championship he is trying to win for the fourth time in five years.
The golf fan was standing 250 yards from the 16th tee at Wentworth's West Course, on the edge of the trees, when he failed to avoid the Scot's wild tee shot.
The ball struck him on top of the head, knocking him briefly unconscious and ricochetted under a bush.
A concerned Monty, leading Anders Hansen of Denmark at 12 under par at the time, waited until the blood-spattered golfer from nearby Ascot was helped into an ambulance before declaring his ball unplayable.
He salvaged a bogey five but the incident took its toll on his concentration and he failed to get up an down from just off the 17th green and found sand twice on the 18th for a bogey six to finish on nine under par.
Hansen had a 65 to lead on 11 under par, with Montgomerie sharing second place with Eduardo Romero (68). Mark McNulty was on eight under par with two to play, alongside Carlos Rodiles (67), while veterans Sam Torrance and Nick Faldo are in a group on five under par. Faldo needs to finish in the top two to continue his record run of 59 consecutive major championships with a place at the US Open next month.
