Ian Holloway has been given a one-match touchline ban and £9,500 fine for his language and behaviour towards match officials after his team's Premier League game against Blackburn on 25 September.
Holloway admitted a Football Association charge of improper conduct after confronting referee Mike Dean in the tunnel following the 2-1 defeat at Bloomfield Road.
The manager was furious Brett Emerton's injury-time winner was allowed to stand despite a suspicion of offside and what he felt was a foul on Gary Taylor-Fletcher in the build-up.
Holloway said after the match: "The referee had a poor game. I can't believe what he saw. There were some unbelievably strange decisions."
The ban will be served with immediate effect, meaning Holloway will not sit in the dugout for this weekend's visit of Manchester City.
