 Clyde were relegated to the second tier, but in the lower division Hood flourished, scoring 37 times from 45 appearances in all competitions during the 1963–64 season as the club gained promotion.This good form continued into the next campaign and, after hesitating over a move to Celtic, the team he had supported in childhood, he was transferred to English club Sunderland for a fee of £30,000 in November 1964.In an early outing for the Roker Park club, Hood scored the only goal of the match against Manchester United, but overall his spell in England was not particularly successful and in October 1966 he returned to Clyde for £13,000.
