UEFA have confirmed the Blues captain will miss Chelsea's next two European matches following his red card in the semi-final second leg against Barcelona.
The defender sat out Chelsea's victory over Bayern Munich in the final, as he served a mandatory one-match ban.
However, UEFA's disciplinary panel added two more games to the suspension, after ruling Terry was guilty of violent conduct when he struck his knee into the back of Barcelona forward Alexis Sanchez in the April 24 clash.
The centre-back is now ineligible for the Super Cup match against Europa League winners Atletico Madrid in August, as well as Chelsea's first Champions League group-stage game in September.
Terry and Chelsea have three days to decide whether to appeal against the decision.
Meanwhile, midfielder Juan Mata has vowed to improve next season despite shining for the Blues since joining the club last summer.
Mata, 24, moved to Stamford Bridge from Valencia last year and was a pivotal part of the side which ended the season with success in both the FA Cup and Champions League under interim manager Roberto Di Matteo.
The Spain international settled straight into the Chelsea side under previous manager Andre Villas-Boas and picked up the club's Player of the Year award but he told Chelsea Magazine he wants to get even better.
He said: "My focus is to continue improving.
"I am young as a footballer and I have to improve my game and my statistics over the next year, this is what I will try to do.
"You cannot rest on what you have achieved, you must look to the future and hope for more success."
With two winners' medals already in his collection as a Chelsea player Mata is also targeting further success with both club and country if it that means he will be very busy in the next few months.
He said: "Lifting the Champions League was an unbelievable experience - the biggest club trophy you can win - and, for me, winning the Player of the Year trophy makes me feel very happy, proud and grateful.
"I could never have expected my first season to go this well. To win the FA Cup, the Champions League and the Chelsea Player of the Year, it is incredible and I am so happy, but I want more.
"I have the European Championships in the summer and maybe the Olympic Games as well, so, who knows, perhaps I can say that I have won nearly everything I have played in this year."
Mata and his Chelsea team-mates are still unaware who will be managing the side next season with a permanent replacement for Villas-Boas still not in place.
The club's chief executive Ron Gourlay said last week a new boss could be in place in as little as two weeks.
A new stadium also remains a priority but reports today suggested they will be ultimately unsuccessful in their application for the site of Battersea Power Station.
Knight Frank, the selling agent for the site, refused to comment but there are up to 14 other candidates for the sought-after location.
