Career
He played as a blindside flanker or Number. 8. He is the younger brother of Leicester and England international Louis Deacon. He left Leicester Tigers at the end of the 2009-2010 season after seven seasons, to play for Gloucester.
In 2012, after being released from Gloucester Rugby he re-joined Leicester Tigers.
On 19 December 2013, Deacon was forced to retire due to a diagnosis of lupus, an autoimmune disease which in his case led to potentially life-threatening blood clots. He was immediately placed on blood thinners.
However, he remained with Leicester Tigers to take a coaching role with their academy.
