He scored just two more goals in the league in the final three months of the season, in a 1–1 draw with Arsenal and a 2–1 victory over Liverpool, but scored in both the quarter-final of the FA Cup against Leicester City and a 3–1 victory over Blackburn Rovers in the semi-final as Cardiff reached their first FA Cup final. He was part of the side selected to play in the 1925 FA Cup Final, losing 1–0 to Sheffield United following a goal from Fred Tunstall. Despite his goal drought, during his time at the club Beadles won two caps for Wales, playing in consecutive matches on 14 and 28 February 1925 against Scotland and England in the 1924–25 British Home Championship. The following year, Beadles scored in the opening game of the 1925–26 season during a 3–2 defeat to Manchester City and scored three times in five further appearances in the opening months of the season. However, despite this form, Beadles was sold to Sheffield Wednesday in order to raise money due to the recession and the arrival of Joe Cassidy from Bolton Wanderers.
