Mark Clattenburg will referee his first Chelsea match in six months this Sunday after being accused of using a racist slur in Chelsea’s game against Manchester United from October, 2012.

Chelsea midfielder John Obi Mikel was the center of the storm after accusing Clattenburg  of using inappropriate language in his team’s match against United, where United won the match 3-2. Chelsea filed an official complaint to The FA, but Sir Alex Ferguson was convinced that Clattenburg was innocent.

The FA led an investigation into the matter, where they removed him from matches while the investigation was undergoing.

After The FA investigation was completed, Mark Clattenburg was cleared of using racist abuse.

Clattenburg will officiate Chelsea’s match against Swansea this Sunday, April 28 at Stamford Bridge.
