Premier League official Andre Marriner has been appointed referee for Sheffield Wednesday's FA Cup fourth round trip to Chelsea.
The West Midlands-based whistler has taken charge of 20 matches this season, dishing out 59 bookings and two red cards.
Marriner has not officiated an Owls fixture since their Championship play-off semi-final second leg at home to Huddersfield Town in May 2017.
The 48-year-old, who was a Football League assistant referee for three years before being promoted to the position of referee in 2003, will be assisted by Stuart Burt and Sian Massey-Ellis at Stamford Bridge on Sunday. Graham Scott is on VAR (Video Assistant Referee) duties and will be assisted by Simon Bennett.
