There was major disruption to the format of the 1941 championship due to a serious outbreak of
foot-and-mouth disease in many parts of
Munster and south
Leinster. The championship was run on a knockout provincial basis as usual; however, there was a certain amount of tweaking required to cope with the situation. Dublin, for instance, did not contest the All-Ireland semi-final as Leinster champions; they were nominated to play the game and their Leinster final against
Carlow (which Dublin won) was postponed until November. ==Munster Championship format change==
