1986–87 Yorkshire Cup
The 1986–87 Yorkshire Cup was the seventy-ninth occasion on which the Yorkshire Cup competition was held. This season there were no junior/amateur clubs taking part, and no "leavers", but another new entrant in the form of Mansfield Marksman and so the total of entries increases by one up to eighteen. This in turn resulted in the necessity to increase the number of matches in the preliminary round to reduce the number of clubs entering the first round to sixteen. In a repeat of the 1983–84 Yorkshire Cup's final pairing, Castleford turned the tables, reversing  the result and beating Hull F.C. by the score of 31-24 to win the trophy. The match was played at Headingley, Leeds, now in West Yorkshire. The attendance was 11,132 and receipts were £31,888. This was the fourth time in the incredible eleven-year period in which Castleford. previously only once winners in 1977, will make eight appearances in the Yorkshire Cup final, winning on four and ending as runner-up on four occasions. Background. The Rugby League Yorkshire Cup competition was a knock-out competition between (mainly professional) rugby league clubs from the county of Yorkshire. The  actual area was at times increased to encompass other teams from outside the county such as Newcastle, Mansfield, Coventry, and even London (in the form of Acton & Willesden). The Rugby League season always (until the onset of "Summer Rugby" in 1996) ran from around August-time through to around May-time and this competition always took place early in the season, in the Autumn, with the final taking place in (or just before) December (The only exception to this was when disruption of the fixture list was caused during, and immediately after, the two World Wars) Competition and Results.
