Boro's match against Cardiff City on Saturday February 27 has been selected for international broadcast.
This means that some overseas Boro supporters will be unable to watch via Matchday LIVE, as rights to show the game are held by the EFL's international broadcast partners.
That is with the exception of areas described as 'Dark Markets' - countries or territories that do not have a broadcaster with an agreement in place with the EFL.
A list of the EFL's overseas broadcast partners can be found here. Countries and territories which are NOT included are 'Dark Markets', and supporters based there will still be able to buy a match pass or use their seasonal subscription.
UK-based fans will also be able to use their Season Card entitlement or buy a match pass and watch via Matchday LIVE as usual.
