It might have been more than three weeks since Halloween, but there was a spooky sight for viewers watching the Monday Night Football between West Brom and Burnley.
As Johann Berg Gudmundsson stepped up to take a corner during Sean Dyche's side's 4-0 defeat at The Hawthorns, many people spotted something peculiar in the background.
As two ballboys sat watching the Icelandic international preparing to take the set piece, it seemed the one on the left didn't have a face.
The unusual episode led to a barrage of tweets about the mysterious ball boy - particularly as the one on the right carried on conversing with him as normal.
On a night when little went right for visiting manager Dyche and his team, it was a light-hearted moment which would surely have made even the Burnley boss smile when he heard about it after the match.
