Songo’o was sent off after using foul and abusive language towards a Tranmere player in the 45th minute of their 1-0 home defeat on Jan. 30.
The FA said the language also constituted an “aggravated breach” as it included a reference to sexual orientation.
“The suspension … includes two matches that have already been served. As a result, Yann Songo’o will be unavailable for Morecambe FC’s next four matches,” the FA said in a statement.
Songo’o, who will also have to complete face-to-face education, said the term he used was unacceptable.
“I’d like to offer a sincere apology for any offence I’ve caused,” he said in a club statement. “I’m really disappointed in myself for using that term, it does not reflect the type of person I am but was under provocation.”
Morecambe said they accepted the FA’s findings.
“We are a community-based family club that has high expectations of its players and staff and Yann’s behaviour fell short of those expectations in this instance,” the club said.
