“Not enough international reach” official IPC reason. The IPC decided to cut 7-a-side Football in 2016, along with Sailing (which was a huge shock). Both of those sports did apply to be continued on the 2020 program. The sports that also went for inclusion were Badminton, Taekwondo, Powerchair Football, Amputee Football, Electric Wheelchair Hockey, and 3x3 Intellectually Impaired Wheelchair Beasketball. Obviously Badminton (which definitely deserved a place) and Taekwondo (not so sure about that one) were selected. The IPC almost decided to cut Track Cycling too.
