Signed on non-contract terms on 31st October 2008. Forrester joined the club following a short spell training with the first team whilst still with Ryman Division One South side Metropolitan Police. His manager at the Surrey side, Jim Cooper said "I allowed Scott to train with Grays having had a conversation with Wayne Burnett. Scott is suspended so it made sense at this time. Opportunities like this don't come along often and there was no way I would stand in his way even though we didn't want him to go." His previous sides also include Leatherhead, Hayes, Sutton United, AFC Wimbledon and Aldershot Town.
Forrester was released on 19th January 2009.
