England’s Six Nations match with Ireland was abruptly stopped in the first half as referee Andrea Piardi had to leave the pitch in pain after something “popped” in his leg. The Italian official had overseen the first 29 minutes before going down and medics rushed to his aid in the hosts’ half at Twickenham.

It became quickly clear that he would not be able to continue, informing the sidelines that a replacement would be needed for the remainder of the match. Piardi was able to get to his feet and informed both captains, Maro Itoje and Caelan Doris, that he needed to be withdrawn.

The referee hobbled off without the use of a stretcher, in positive news, after ITV commentator Nick Mullins claimed he heard the ref say “I heard it pop”.

Piardi then told the skippers: “I’m out, my quad’s gone. Best of luck for the rest of the game. 29 minutes played.”

Ireland had already rampaged into a 15-0 lead as a result of tries from Jamison Gibson-Park and Robert Baloucoune.

The first half saw multiple changes, in addition to Piardi’s injury, with James Lowe forced off with his own issue and replaced by Tommy O’Brien.

On the stroke of half-time, after the visitors had extended their advantage to 22-0, Freddie Steward also had to be replaced as Marcus Smith joined the fray from the bench.

England were able to get a much-needed try just before the break, as Smith’s delayed pas found Fraser Dingwall to power over from close range.
