The umpire's identity was meant to be concealed for "security" reasons, but the back of his head and body was shown, as was the lower half of his face.
And several viewers were left wondering why his entire face couldn't be shown, as he was recognisable from what had been shown on TV.
Ryan Glendenning said: "I love the umpire I wander what he looks like (crying laughing emoji)"
Lynsey Thompson said: "They are not the best at covering up the umpires face."
Lucy Wynne said: "Why can’t they show the umpires full face but they can show the whole bottom half of his face and the whole back of his head/ears? I don’t get it ?"
And Tom said: "If the umpire is that high security why are they showing parts where u can see 3/4 of his face."
