Steven Gerrard’s footballer cousin told a fan on Twitter he had bedded his mum.
Anthony Gerrard, cousin of the former England midfielder, taunted Chesterfield supporters who asked why he had been benched.
The injured defender watched from the stands as his team won 1-0 against Torquay United on Saturday.
One of the club’s fans then tweeted: “What’s your excuse this week, fat boy?”
Club captain Gerrard, 33, quipped: “Pulled my hammy last Saturday night while I was rifling your mother, hope that clears that up.”
Another fan caught up in the row was told by the footballer to repeat the abuse to him face-to-face.
Gerrard said: “You’ve got far too much to say for yourself fella, come to the ground on Tuesday and voice your opinion while your standing in front of me, rather than acting brave behind your phone, look forward to seeing you.”
When the supporter asked: “Does 8am suit you?” the Scouser replied: “Say 9, let my full English settle.”
It is not the first time Gerrard has been pulled up for his social media use. He was sacked by Oldham Athletic after allegedly posting a racist joke in a players’ WhatsApp group.
Last night Chesterfield confirmed Gerrard had received a “significant” fine.
The player apologised and said in a statement: “I accept that I was wrong to respond to messages sent to me via social media.
“It was not my intention to bring the club into disrepute.”
Chief executive Graham Bean said the club condemned the posting of inappropriate content.
