Ex-Hitchin player Alfie Barker has been charged by the FA in relation to tweets sent to Bournemouth's Harry Arter about the death of his baby daughter.
Bournemouth lost a three-goal lead to draw 3-3 with Arsenal in the Premier League on Tuesday, 3 January.
Barker, on Hitchin's books at the time, later posted: "Big hype just for a disappointment like the nine months leading up to your child's birth."
Barker, who was sacked, has until 25 January to respond to the charge.
He later apologised for his "disgraceful comments" and said that he would accept any punishment given to him.
