In May he was appointed to assist Philip Don once more, this time in the 1994 European Cup Final between AC Milan and Barcelona.
He took charge of a greater number of games, including play-off matches, and in 1998 he was promoted to the Premier League referees List.
Harris served as a Premier referee for three seasons but three major incidents marred this period.
In January 2000 he sent off Clint Hill of Tranmere near the end of their home FA Cup tie with Sunderland.
[3] As Hill was leaving the field Tranmere made a substitution but in the confusion no player was actually withdrawn.
None of the officials noticed this, and the home team continued to play with eleven men rather than ten in the final minutes.
In August 2000 he had moved from Oxford to the Isle of Wight, making him the first National List referee from this location.¶ (James Linington a current Football League referee is from the Isle of Wight) He only remained on the Football League for this one season (2001-02), before he resigned to become an Assessor for the 2002–03 and 2003-04 seasons.
