In 1987, after nearly three seasons with the Bantams, he moved to fellow Division Two club West Bromwich Albion. Over the next four years, he scored his highest club tally, netting 60 league goals. However, despite his impressive performances, West Bromwich Albion suffered relegation to the third tier in 1991, the first time in their history.
Don’s time in the third tier was brief, as he joined Sunderland in December 1991 for £900,000. Over the next three years at Roker Park, Sunderland remained mid-table in Division Two but reached the 1992 FA Cup Final. Unfortunately, Don was unable to play in the final due to being cup-tied, having already participated for West Bromwich Albion earlier in the competition.
In December 1994, Don moved to Wolverhampton Wanderers for £1.1 million in pursuit of top-flight football. He helped the club reach the play-offs twice in three seasons, but they fell at the semi-final stage both times. During his final season at Wolves (1997–98), Don scored the winning goal against Leeds United, securing a place in the FA Cup semi-finals for the first time in 17 years. However, his time at Wolves was plagued by injuries, including a fractured skull. After failing to reach the play-offs, he was given a free transfer in May 1998 as part of a player clear-out by manager Mark McGhee.
In search of a new challenge, Don moved to Japan, joining Sanfrecce Hiroshima, though his stay was short-lived. He was loaned back to Britain, playing for Barnsley and Motherwell. His time at Motherwell became permanent in the summer of 1999, and he spent almost two seasons in the Scottish Premier League.
In March 2001, Don returned to the West Midlands, joining Division Three club Walsall on a free transfer. In 25 appearances, he scored three goals, with one crucial strike in the play-off final against Reading that secured Walsall’s promotion to the second tier. After another season at Walsall, he moved to Exeter City but finished the 2002–03 season on loan at Conference side Doncaster Rovers. Don wrapped up his playing career with a season at non-league Stafford Rangers before announcing his retirement.
Since retiring, Don has worked extensively in the media and television, including as a regular contributor for Sky Sports.
He is also a highly regarded after-dinner speaker, known for his friendly and approachable personality, which has made him a popular figure on the circuit.
