As Boro put in the groundwork for Saturday's trip to the Welsh capital, here's a look back at a classic against Cardiff City.
With the two teams battling it out in Division Two throughout the 1960s, matches involving Boro and the Bluebirds had often proved high-scoring affairs. The decade saw two 3-2s and two 4-3s between the sides, as well as a 6-1 and 5-3 in the Welsh club's favour.
This league meeting at Ninian Park in October 1970 proved no different.
Boro were in fine goalscoring fettle heading to South Wales, but the defending of Stan Anderson's team left a bit to be desired. In fact, this match marked the centre of a five-game spell that saw Boro net 17 goals, but concede 13 as well.
John Hickton, who would finish top scorer with 27 that season, headed in Boro's opener with 20 minutes played, but Brian Clark nodded Cardiff level ten minutes later.
Heading into the second half, and a couple of wonderful long-range strikes from Bobby Woodruff and Peter King swung it in the home side's favour. The second in particular, an exceptional first-time volley from out wide, will live long in the memory of Cardiff fans.
But it was Boro who would celebrate victory that day.
A collector's item, a penalty miss from Hickton, didn't deter the Teessiders, who reduced the deficit thanks to a more welcome rarity, a goal from defender Willie Maddren.
Joe Laidlaw scrambled in an equaliser with twenty minutes to play, before Hugh McIlmoyle stole the three points for Boro with a late header.
Despite the early dramas, Boro's campaign would somewhat fizzle out. Eight games squeezed into the final month of the season, remarkably, all finished in draws on the way to a seventh-place finish.
Cardiff, meanwhile, missed out on promotion by one place, finishing third. The Bluebirds also played Real Madrid in the quarter final of the European Cup Winners' Cup, winning the first leg 1-0 on home soil in what remains one of the club's most memorable triumphs.
