Holloway admitted a Football Association charge of improper conduct after confronting referee Mike Dean in the tunnel following the 2-1 loss at Bloomfield Road.
The Seasiders boss 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: "I thought the referee had a poor game and he is going to report me for what I said to him in the tunnel.
"I can't believe what he saw. I thought there were some unbelievably strange decisions out there.
"I waited for him in the tunnel. Never mind, I have got to learn and I should know better - but it is ridiculous.''
A regulatory commission heard the case on Tuesday, taking into consideration a previous incident on his disciplinary record - when he served a two-match touchline ban for improper conduct towards a match official at Blackpool's meeting with Ipswich in January.
The ban will be served with immediate effect, meaning he will not be in the dugout when Manchester City visit Bloomfield Road this weekend.
Blackpool defender Craig Cathcart has withdrawn from Northern Ireland's Euro 2012 qualifier against the Faroe Islands on Tuesday after failing to recover from a back injury.Centre-half Cathcart will not travel to Toftir, Northern Ireland managed Nigel Worthington has confirmed.
The 21-year-old, who moved to Blackpool from Manchester United this year, had already sat out Friday's 0-0 draw with Italy after suffering a back spasm in his club's 2-0 win at Liverpool.Northern Ireland are unbeaten in two games in qualifying.
Blackpool midfielder David Vaughan believes Wales would have a bright future under Brian Flynn - if the players can secure the manager's job for him this week.Wales face Switzerland in Basle on Tuesday in the second and final match of Flynn's spell as caretaker boss, needing to win to retain any realistic hope of qualifying for Euro 2012.
Flynn was put in charge for this month's double-header against Bulgaria and the Swiss, and after defeat in the first of those matches on Friday he now has just one remaining chance - on his 55th birthday - to impress.
Wales have no points after two games in Group G and another loss would all-but end their campaign just a month after it began.Vaughan said: "We have just got to pick ourselves up for Tuesday.
We have only had a few days' training with him [Flynn] but if he is around long term I think you will see the benefits in the performances."No one wants to let him down and hopefully he will get the job, regardless of the results, if we play well. Hopefully we can do the job for him.
It is going to be very difficult to qualify but we have just got to try to win every game and we will see where we go."
