The fiery Spanish international has been punished for his unruly behaviour during his sending-off against Everton in an FA Cup tie on 12 March, with interim manager Guus Hiddink suggesting afterwards he’ll have to watch the movie “Anger Management” with the striker.
Costa clashed with Toffees midfielder Gareth Barry and moved in on him as if to bite, although the England international later said no contact had been made.
Everton won the FA Cup quarter-final clash 2-0 at Goodison Park with former Chelsea boy Romelu Lukaku netting a brace, and Costa was sent off in the 84th minute for two bookable offences – the first on-pitch red card of his Chelsea career.
Costa was originally handed a two-match ban, but will now miss three games, the first of those was the 2-2 draw with West Ham on 19 March and he is suspended for Saturday’s trip to Villa Park to take on relegation-bound Aston Villa.
Costa, who has also been warned as to his future conduct, will now be absent for his side’s trip to Swansea on 9 April.
However, he originally received a two-game automatic ban as it was considered to be his second dismissal of the season after he was given a retrospective three-match ban for altercations with Arsenal’s Laurent Koscielny and Gabriel in September.
The former Atletico Madrid striker helped Chelsea win the Premier League title last season and has scored 11 goals in his last 16 games under Hiddink.
