Scottish striker Ross Jack joined Norwich from Everton for £20,000 in December 1979 having made one appearance for the Toffeemen, scoring in that match. Everton had signed him from Ross County and had also loaned him to Cardiff City. Converted at Norwich into an attacking midfield role, he made his City debut against Ipswich in the League Cup in September 1980. The 1981/82 season was the highlight of his career in England when he scored in 6 successive games and eventually was leading scorer. A goal drought the following season led to a £15,000 transfer to Lincoln City for whom he played 60 league games scoring 16 goals. This added to 1 goal and game for Everton and 67games and 14 goals for Norwich.

In July 1985, he returned to Scotland to join Dundee. After 38 matches and 4 goals, he moved on to Dunfermline in October 1987. 46 goals in 130 games followed and in the 1989/90 season was second highest goalscorer in the Scottish Premier League. In July 1991, he joined Kilmarnock (55 games, 13 goals) before becoming the player-manager of Montrose in March 1993. Managerial responsibilities limited appearances and this spell generated just 6 matches although 2 goals were scored. In October 1993, he joined Ayr United. According to Mike Davage's excellent article "Canaries Flown From The Nest" in the 1998/99 club handbook, Ross is working as a Scottish Football Association development officer in Dingwall.

He later worked as a high performance football coach at the Scottish Insistute of Sport in Stirling. However Jack was disappointed when his post with the Scottish Institute of Sport was axed in April 2008, insisting that the programme was working well.

On 2nd July 2008, he was appointed asssistant coach at Ross County. He was sacked in early December 2008 with the management team "wanting to take a new direction". In January 2009, he was linked with the management vacancy at Elgin City. He was successful in his application, being appointed to this position on 22nd January 2009. It is possibly the most challenging job in Scottish football with Elgin rooted to the bottom of Scottish Division Three.

He said: “I am thrilled as it is a great place to start my managerial career. I do realise there is a difference between a coach and a manager but I have learned my trade, come through the system, and I am very confident I can do it as a manager. I have been given a three-and-a-half year contract and I am very confident we can start progressing in the right direction. At the same time there is no pressure on me this season, or even the next, but I hope to build beneath the first-team a good, strong youth structure from primary right through secondary school level, so if I go the legacy is nice and strong. I will be part-time until the end of the season when we can assess and look at the whole set-up, as first and foremost we have to prove we can make the whole thing work. The perfect scenario for us would be local talent training on the doorstep and not paying a fortune in travel expenses – if we can it would be a win-win situation – and that really would be ideal.”

After five years with the club, Jack left Elgin City in January 2014 by mutual consent. On 23rd April 2014, Jack was appointed manager of Turriff United a Scottish Highland Football League Club from Aberdeenshire. After four years with Turriff, leading them to their ever-highest position of 2nd place, Jack left them. He took charge of fellow Highland League side Rothes in September 2019.
