Boro will travel to Huddersfield Town in the first round of the Carabao Cup.
Completing fixture release day, with our Sky Bet Championship calendar confirmed earlier in the day, the Teessiders will entertain the Terriers the week commencing 7 August.
The match will be the start of back-to-back away fixtures for Michael Carrick's side with the cup tie sandwiched in between our opening day meeting with Millwall and the trip to Coventry City.
The 2023/24 season marks 20 years since Boro famously lifted the trophy at the Millennium Stadium, defeating Bolton Wanderers 2-1 in the Welsh capital.
Ticket details will be confirmed in due course.
