SOFIA (Reuters) -- Bulgarian referee Nikolay Yordanov has been banned for two months after making mistakes in the champions Litex Lovech's 2-1 win at Pirin Blagoevgrad on Saturday.

Yordanov's ban, imposed by the Bulgarian Football Union (BFU) on Tuesday, came after a furious protest from Pirin over his failure to penalise Litex's Brazilian winger Doka Madureira for a head-butt on Anton Kostadinov early in the second half.

Soon after the incident, Doka scored Litex's equaliser and he also assisted Senegalese striker Pape Diouf's winning goal five minutes from time.

"The punishment is rather symbolic," Pirin's chief executive Emil Nakov told local media. "They should ban such referees for life."

Leaders Litex also complained, saying Yordanov failed to award what looked an obvious penalty during the hard-fought victory over relegation-threatened Pirin.

In 2008, Yordanov was suspended for four matches after making a series of blunders in a game that ended a 33-match unbeaten league run for then-champions CSKA Sofia.

Yordanov became Bulgaria's second UEFA referee to be banned this season after Angel Angelov was suspended until the end of the season in November.
