It proved to be his only appearance for the club and he left for Brighton in May 1966.  He spent two-and-a-half years on the south coast, including a four-month loan spell with the Baltimore Bays in the North American Soccer League (NASL) between April and August 1968, before joining Fulham in January 1969.
