The Poland international was dismissed in the 68th minute of the match at Upton Park for impeding West Ham substitute Diafra Sakho as he burst through on goal.
However, Swansea manager Garry Monk said after the 3-1 loss that he expected the club to appeal the decision, saying there was both a handball by Sakho in the build-up and that it was not a clear goalscoring opportunity either, and on Monday the Welsh club confirmed they had been in touch with the FA
A statement read: " Swansea City can confirm that the club will be appealing the red card issued to goalkeeper Lukasz Fabianski against West Ham on Sunday
"The club officially informed the Football Association by today's 1pm deadline.
"The Polish international, who faces a one-match ban, was shown a straight red card by referee Chris Foy for impeding Diafra Sakho and denying a clear goalscoring opportunity in the 68th minute of the defeat at the Boleyn Ground.
"The FA will make a decision on the appeal ahead of Sunday's Barclays Premier League clash with Spurs at the Liberty Stadium."
