The FA want to speak to Southampton striker Charlie Austin following his apparent two-finger salute to supporters during their defeat by Manchester City.
Austin has been asked to explain the signal he made as he ran off the St Mary's pitch to be replaced by Shane Long in the 68th minute.
The 29-year-old was booed on his jog towards the dugout and appeared to respond by flicking two fingers up at the crowd.
City won the game 3-1 thanks to goals from David Silva, Sergio Aguero an own goal from the unfortunate James Ward-Prowse.
But things could get worse for Saints if Austin lands himself in hot water with the FA, who are 'seeking observations' from the forward.
The incident comes five years after then-Arsenal midfielder Jack Wilshere was banned for two games for making an offensive gesture to Manchester City fans.
England star Dele Alli was also suspended for one match last year for a 'offensive and unsporting' gesture during a 2-1 victory over Slovakia.
It remains uncertain whether there will be similar repercussions for Austin, who has scored three goals for Saints this season.
