The official has been accused of racially abusing Chelsea midfielder John Obi Mikel but must now await a verdict from the English football governing bodyThe Football Association's investigation into referee Mark Clattenburg's alleged racial abuse of Chelsea midfielder John Obi Mikel is expected to end on Friday.
The 37-year-old was accused of using "inappropriate" language to the Nigerian and his team-mate Juan Mata during last month's clash between the Blues and Manchester United at Stamford Bridge - though the latter allegation was later dropped.
Clattenburg has denied any wrongdoing, claiming he was "baffled" by the statement given by the west London side just hours after their controversial 3-2 defeat to the Red Devils.
Since then, witness statements have been made by both parties, including all the officials present at the game who were able to hear verbal exchanges through an open microphone system.
The County Durham-born official now looks set to miss a second week of officiating as he awaits a verdict from the FA.
