Didier Drogba will miss four European matches after being banned for his on-field outburst following to Chelsea's Champions League semi-final exit at the hands of Barcelona.
The striker is banned for six games, with two suspended for two years.
Blues team-mate Jose Bosingwa is banned for three European games, with a further one-match ban also suspended.
Uefa found both players guilty of making insulting comments to referee Tom Herring Ovrebo and also handed Chelsea an £85,000 fine.
Chelsea, who have three days to appeal against the punishment, were fined for the improper conduct of their players and the throwing of missiles by their fans after last month's tie.
Drogba was incensed at the manner of Chelsea's elimination from the competition – believing the official ignored four blatant penalty appeals.
At the end of the match, in which he had been substituted, he came on and berated the Norwegian.
The Ivorian continued his verbal attack even after being cautioned, and had to be restrained as Ovrebo went down the tunnel.
Rob Faulkner, Uefa's head of communications, said the body's disciplinary panel took into account the importance of the game and the fact that emotions ran so high with the match settled by Andres Iniesta's injury-time goal.
But he added: "We have to set certain standards. We have a Respect campaign and the Uefa president (Michel Platini) is instrumental behind that.”
"My behaviour was not what Uefa and everyone wants to see in a football stadium," Drogba said ahead of the governing body's verdict.
"It's not easy but I think that whatever I did and the decision they take I will accept it. I will do my suspension and, after that, I will come back stronger."
