The Bulgarian Football Union (BFU) has announced that referee Hristo Ristoskov has been suspended once more for making too many mistakes.
Ristoskov was in charge of CSKA Sofia's 2-1 victory over Ludogorets in the Bulgarian Cup on Wednesday, but the victors were incensed after his decision not to award two penalties, among other errors.
CSKA sent a complaint to the country's refereeing commission and said: "The management of CSKA Sofia, despite winning the game, wish to express their indignation at the manner in which it was refereed.
"We believe that his officiating was extremely biased, to the detriment of CSKA, and inconsistent with the rules of refereeing."
Reuters reported that Ivan Bandalovski, the CSKA captain, had said he had "never seen such refereeing" and that "you must be blind or crazy to not see what's going on".
Nikola Dzhuganski, the BFU refereeing commission chief, has now said Ristoskov will not officiate in another match before Christmas.
"Ristoskov was responsible for many errors in both directions," he added in the Meridian Match newspaper. "His performance was definitely not satisfactory."
The 41-year-old referee had previously been issued with a four-match BFU ban after making a number of mistakes, and afterwards went to referee in the Austrian lower divisions.
He was also attacked by three masked men in Bulgaria in 2006 in the wake of his performance in the "Eternal Derby" between Levski Sofia and CSKA.
In 2011, he claimed to have been offered a bribe to fix a UEFA Cup preliminary round match between Neftchi Baku of Azerbaijan and Austria's SV Ried. "I was offered $100,000 but I rejected it immediately," he told Kanal 3.
