* ^¹ = Played For Castleford (Tigers) During More Than One Period
* ^² = drop-goals are currently worth 1-point, but from the 1897–98 season to prior to the 1973–74 season all goals, whether; conversions, penalties, or drop-goals, scored two points, consequently during this time drop-goals were often not explicitly documented, and "0" indicates that drop-goals may not have been recorded, rather than no drop-goals scored. In addition, prior to the 1949–50 season, the Field-goal was also still a valid means of scoring points
* ^³ = During the first two seasons of the Northern Union (now known as the Rugby Football League), i.e. the 1895–96 season and 1896–97 season, conversions were worth 2-points, penalty goals 3-points and drop goals 4-points
* ¢ = player has (potential) links to other rugby league clubs on Wikipedia
* BBC = BBC2 Floodlit Trophy
* CC = Challenge Cup
