The Football Association will launch an investigation after an elderly fan was injured by a smoke grenade.
The Saints supporter was watching Southampton FC take on AFC Bournemouth at the Vitality Stadium, in Bournemouth, on 19 October.
The man was hit by a smoke grenade discharged during the match and treated by the medical staff at the site before returning to his seat.
The FA said it would investigate the incident.
To whoever let off one of the Smoke Grenades in the away end tonight. You have injured an elderly fellow Southampton fan.
