Seven-a-side football is an adaptation of association football for athletes with cerebral palsy and other neurological disorders, including stroke and traumatic brain injury. The sport is governed by the International Federation of Cerebral Palsy Football (IFCPF). The sport is played with modified FIFA rules. Among the modifications are a reduced field of play, a reduction in the number of players, elimination of the offside rule, and permission for one-handed throw-ins. Matches consist of two 30-minute halves, with a 15-minute half-time break.
Players competing in 7-a-side football are given a sport class based on their level of disability. Eligible classes are:
- C5: Athletes with difficulties when walking and running, but not in standing or when kicking the ball.
- C6: Athletes with control and co-ordination problems of their upper limbs, especially when running.
- C7: Athletes with hemiplegia.
- C8: Minimally disabled athletes; they must meet eligibility criteria and have an obvious impairment that has impact on the sport of football.
Teams must field at least one class C5 or C6 player at all times. No more than one players of class C8 are permitted to play at the same time.
