Ref Mark Halsey is considering calling in the police after suffering sick Twitter abuse in the aftermath of Manchester United's win at Liverpool.

The Daily Mail says a number of tweets referred to Halsey's well-known battle against cancer and sickeningly referred to his wife, Michelle, who has also been fighting the disease.

Halsey and his family were so upset by the tweets that the referees' governing body, Professional Game Match Officials Ltd, will offer Halsey the chance to consult a psychologist and replace him for his Capital One Cup tie on Tuesday between Southampton and Sheffield Wednesday.
