In January 2000 he sent off Clint Hill of Tranmere near the end of their home FA Cup tie with Sunderland. As Hill was leaving the field Tranmere made a substitution but in the confusion no player was actually withdrawn.

This error of Law is treated very seriously, and as a result Harris was suspended and did not officiate again for another two months.‡
