Brunt, who received a straight red card for a slightly mistimed tackle in the 1-1 draw with Groningen, will be absent for the League Cup clash with Rotherham as well as the home game with Wolves and the away trip to Charlton.
The incident where the Northern Ireland star was dismissed was harsh at best and although Wednesday appealed the decision, the ban will stand after the FA received the Dutch referee's report.
Deon Burton is also walking on a tightrope and he could follow Brunt by watching for the stands after he too got dismissed in Holland.
The Jamaica international was sent off against Heerenveen for not immediately walking towards the referee when summoned.
Wednesday will be anxiously waiting to see the report from that game which is currently at the FA's Soho Square headquarters and is waiting to be translated from Dutch to English.
The double blow has also been hampered with the news that Brunt has rejected an improved contract, Jermaine Johnson could not fly to the Netherlands for work permit problems, Brian Laws has had no luck attracting a new striker to the club and below-par performances against Port Vale (0-3) and Oldham (0-2).
