On this day in 2015, Boro's Play-Off dream ended in heartbreak at Wembley - a cruel end to a remarkable campaign.
In Aitor Karanka's first full season at the helm, Boro emerged as one of the must-watch teams in the Championship - striding towards the top end of the table with a swagger while also putting some of the nation's heavyweights to the sword in the cup competitions.
All of Teesside seemed to make the trip to the capital for the Play-Off final, congregating in Trafalgar Square on the eve of the fixture before descending on Wembley.
Though our dreams of a top flight return were halted on the biggest stage by Norwich City, team and fans had come together to enjoy a scintillating season.
And it made Boro's achievement of promotion a year down the line all the sweeter.
