Don Metcalfe played at centre in Featherstone Rovers' 10–18 defeat by Workington Town in the 1951–52 Challenge Cup Final during the 1951–52 season at Wembley Stadium, London on Saturday 19 April 1952, in front of a crowd of 72,093.

Don Metcalfe played at centre, and scored three tries in Wakefield Trinity's 20–24 defeat by Leeds in the 1958 Yorkshire Cup Final during the 1958–59 season at Odsal Stadium, Bradford on Saturday 18 October 1958, played fullback in the 16–10 victory over Huddersfield in the 1960 Yorkshire Cup Final during the 1960–61 season at Headingley, Leeds on Saturday 29 October 1960, and played fullback in the 18–2 victory over Leeds in the 1964 Yorkshire Cup Final during the 1964–65 season at Fartown Ground, Huddersfield on Saturday 31 October 1964.

This season Don's appearances have been almost equally divided between centre and fullback and his utility qualities have been of great service to Wakefield Trinity in recent months.

Don Metcalfe, the present Wakefield Trinity player, who joined the club from Featherstone Rovers in April 1957, continues a remarkable family association.

Before that his grandfathers, J. D. Metcalfe and E. W. Bennett gave long and valued service and, still further back, his great-grandfather, T. O. Bennett was a player in the club's earliest days, a founder member, and at one time honorary secretary"[6] Don Metcalfe was also the nephew of the rugby league footballer, and coach, Stan Smith.
