Leicester Tigers head coach Geoff Parling was visibly angered by TNT Sports broadcasters for interfering with his side’s warm-up.The PREM Rugby side were preparing to face Gloucester in the Slater Cup on Saturday afternoon, with TNT providing match coverage.MacDevitt’s conversion did not impress Parling@Enge21 XPositioned on the touchline at Villa Park, home of Premier League side Aston Villa, presenter Craig Doyle was joined by producer Liam MacDevitt.MacDevitt was tasked with attempting a conversion, with the former footballer aiming for the posts where Leicester were practising.It was dressed up as an ‘initiation’ process – given MacDevitt is a new member of the production staff.His effort went wide of the target, as as the ball landed close to the Leicester squad, the lighthearted pre-match kick did not go down well with Parling.‘That’s not on’Shortly after, the former England international walked over to the broadcasting duo while shaking his head in clear disapproval.“Would you sign him?” Doyle jokingly asked.Parling, clearly livid, pushed Doyle and said: “That’s not on. That’s not f***ing on.”He then ordered the TNT staff off the pitch before Doyle told viewers Parling was ‘understandably upset’. “Geoff’s not happy about that,” the presenter said. “Apologies for the language.”Fortunately for Parling, his Leicester side were not affected by the stray conversion as they went on to beat Gloucester 36-17.View Tweet: https://t.co/89sFyaCBDaThe Slater Cup is named after Ed Slater, who featured for both clubs before retiring in 2022.Slater was diagnosed with motor neurone disease, with the match helping to raise money for his charity 4Ed.The 37-year-old was at Leicester from 2010 to 2017 before moving to Gloucester, the final club of his senior career.Slater was in attendance at Villa Park for the match, with Leicester cruising to victory.England hooker Jamie Blamire scored two tries, both of which came in the opening 16 minutes.Leicester are third in the PREM table, with Northampton Saints at the summit after 11 matches.
