Southampton captain Jack Stephens will serve an additional two-match suspension after already missing three games following his red card against Manchester United.
Stephens was sent off by referee Stuart Attwell for a dangerous challenge on Alejandro Garnacho in the 79th minute of his side's 3-0 home loss.
The 30-year-old was banned for three matches for that red card and he has now been hit with another punishment for his 'improper conduct' after he was dismissed.
He is judged to have used abusive and insulting language towards referee Attwell and fourth official Gavin Ward.
