LONDON (AP) — Play was suspended in the first half of a Premier League match between Brentford and Wolverhampton on Saturday because a drone was hovering above the field.

The players were taken off the field by the referee in the 34th minute with the score at 0-0.

There had already been a long stoppage in play following a sickening clash of heads between Brentford teammates Mathias Jensen and Rico Henry, which left both bleeding heavily. They were both replaced by concussion substitutes.
