Late in Friday's first season in Wales, Cardiff took on Luton Town on 16 April 1977. Cardiff were in the relegation zone and had not won in seven games, while Luton were fifth in the table and challenging for promotion. After clashing repeatedly early in the match with Luton goalkeeper Milija Aleksic, Friday was lectured by the referee for a high tackle on the goalkeeper in the 36th minute. Friday held out a hand to apologise, but Aleksic reacted angrily. When the free kick was taken, Friday ran back, stole the ball from Luton defender John Faulkner, broke away, rounded Aleksic and slotted the ball past him into the net. In celebration, Friday jogged back past the goalkeeper while giving him the V-sign. Cardiff won the match 4–2 and at the end of the season avoided relegation to the third tier only on goal difference. Meanwhile, without Friday, Reading were relegated back to the Fourth Division by one point. Friday's actions became even stranger during his time at Cardiff; after they lost the second leg of the Welsh Cup final 3–0 to Shrewsbury Town on 18 May 1977, the players and staff were awoken in the middle of the night by loud bangs coming from below their rooms. The cause was found to be Friday, standing on the hotel's snooker table in his underpants and throwing the balls around the room in fury.
