Cristiano Ronaldo accidentally KO'd a match steward while warming up for Manchester United's clash at Young Boys.
The Portugal star fired a shot just wide of the goal as he limbered up for the Champions League clash in Switzerland.
The ball cannoned into an unsuspecting steward standing behind the goal and the impact knocked him to the ground on Tuesday evening.
Ronaldo jumped over the barriers to check on the welfare of the stricken steward as he received medical attention.
The Portuguese star also apologised.
