On this day in 2016, Boro drew 1-1 with Brighton and Hove Albion to achieve promotion to the Premier League.
A season of twists and turns at the top end of the Championship table concluded with Boro hosting The Seagulls in a straight showdown for promotion.
Having missed out in the Play-Off final at Wembley the previous year, Boro were all the more determined to secure an automatic spot.
Cristhian Stuani gave us the advantage, and though Dale Stephens - later dismissed for a foul on Gaston Ramirez - would equalise at the same end in the second half, Aitor Karanka's side held their nerve against the ten-man visitors to send the packed out Riverside into jubilant celebrations.
