Mo Farah: Northampton investigate Brett Sharman's Twitter message
Northampton Saints are carrying out internal disciplinary procedures over a comment one of their players made about Mo Farah on Twitter.
South African hooker Brett Sharman has deleted his account since the tweet about Somalia-born Farah.
But BBC Sport has seen the message which read: "Good luck Mohammed running for Paki... I mean Great Britain..."
Sharman posted the tweet on 11 August when Farah won a second Olympic gold in the 5,000m.
The 25-year-old apologised on Twitter the following day.
Saints have not revealed details of any disciplinary action taken against their player, but a club spokesman said: "Northampton Saints treats all such matters seriously.
"The club has a clear policy regarding social media and is following the procedures set out in that policy.
"Northampton Saints does not comment on individual cases."
Sharman joined the Premiership club in November 2008 and is a regular in the club's first team, filling in for Dylan Hartley when the captain is away on England duty.
Farah was born in the Somalia capital, Mogadishu, but came to live in the UK when he was eight years old.
His win in the 5,000m, a week after his gold in the 10,000m, was described by BBC commentator Brendan Foster as "the best moment I've ever witnessed in athletics in Britain".
