Equally competent across the half-back line, Elwood was poached from Glentoran FC by Manchester City FC in January 1924. He made his Football League debut in a 2-2 home draw with Burnley FC on 16 February. Three and a half seasons brought just 32 appearances and he dropped down to Division Three (North) with Chesterfield FC in 1927, and was a virtual ever-present in the clubs battle against having to apply for re-election. He must have impressed in his games against Bradford Park Avenue who finished that season as Division Three (North) champions, as they signed Elwood for the following campaign. Back in Division Two, Elwood earned the attentions of the Ireland selectors and was capped twice in 1929. He gave Bradford four good seasons as they challenged at the top end of the table without making the jump to Division One.
