The former Blackpool manager will miss the Eagles' encounters with Manchester United and Swansea after the south Londoners confirmed the club will not lodge an appeal with the FA
The Eagles' return to the Premier League saw them defeated by a lone Roberto Soldado penalty on Sunday August 18, much to the ire of Holloway.
"It's going to be a long hard season for me with these people," said the irrate manager after the match. "I had this with Blackpool. Certain clubs get fouls and others don't. I just want a bit of fairness."

The Eagles boss will also pay an £18,000 fine after admitting two seperate charges, and will miss his side's upcoming ties against Manchester United and Swansea.
On Wednesday an Independent Regulatory Commission hearing found that the Englishman had run afoul of FA Rule E3 on two separate counts.
Holloway was found to be in brech of rules regarding "language and/or behaviour in or around the match officials' changing room after the game" and "post-match comments [which] constituted improper conduct in that they questioned the integrity of the match referee and/or match officials in general, and/or implied that the match referee and/or match officials in general were motivated by bias; and/or brought the game into disrepute."
The violations carry an immediate two-match ban and a £10,000 penalty, and an £8,000 fine, respectively.
