Wayne Barnes will break the record for the most Premiership games refereed when he takes charge of Worcester’s match against London Irish on Friday.
The 38-year-old Englishman will surpass Chris White, who officiated 190 league games between 1997 and 2011, on the all-time list.
Barnes turned professional in 2005 and has overseen seven Premiership finals since 2008.
He has refereed at three World Cups and been in the middle for 77 Tests.
