The 'buy one, get one for free' offer means that season ticket holders can get two adult tickets from just £23, instead of the usual £46. Other prices for the match are East and West Lower, £26; East Upper, £30; West Upper, £31. Unfortunately, there are no matchday tickets available for the North Stand.
The special offer tickets are available from the main Riverside ticket office now. Voucher R from season ticket books is required with each purchase.
Unfortunately, the offer is not available via telephone or internet bookings.
The offer covers full-priced tickets only and does not include tickets that are already discounted for those aged under 16 or over 65.
Graham Fordy, Boro's Head of Commercial, said: "This is another way of rewarding our season ticket holders for their loyalty and support.
"We hope they will take the chance to bring along their family and friends to this important fixture, helping to boost the attendance on the night. It's a vital match for the club and a large crowd will make a big difference for the players."
