Known for his lightning pace, Newby began his career with
Liverpool, and was involved in their
FA Youth Cup win of
1996. He made four appearances for Liverpool (only one of which was in the
Premier League against
Middlesbrough), and was loaned out to
Crewe Alexandra (March 2000),
Sheffield United (
August 2000), and Bury (February 2001). This final loan move was made permanent, with Bury getting him on a free transfer on 20 March 2001. In summer
2003 he moved on to
Huddersfield, but the move was not a success, and following a loan spell at
York City, he returned to Bury a year later. He had a loan spell with
Kidderminster Harriers during the
2005/06 season, but later returned to
Gigg Lane. "
Newbs" as he is affectionately known by the Gigg Lane fans was released in May 2006 after failing to break his way back into the first team. He subsequently joined
Wrexham for a short spell before leaving the club in December 2006. He joined
Southport the following month but was released in May after the club were relegated from the
Conference National. Newby signed for
Morecambe after a trial period in August 2007. His first professional
hat-trick came against
Rotherham United in March 2008, scoring all three goals in the first half and helped Morecambe to a 5–1 victory in a surprising good season for the club. This was also Morecambe's first hat-trick in
the football league. After a great season at Morecambe where he finished joint top scorer he was released by manager Sammy McIlroy to the fans dismay. A strange statistical anomaly makes weird reading, Newby has been loaned out seven times in his career, yet failed to score at six of those clubs. Newby signed for
Scottish First Division side
Greenock Morton in July 2008, before going on to score a double that evening in a friendly match against
Threave Rovers. He scored on his competitive debut, a 1–1 draw at Broadwood against
Clyde. Newby was loaned to
Nigel Clough's
Burton Albion, as he was travelling up to Greenock from his home in England, just before the 1 September transfer window deadline. Clough confirmed after the win over
York City that Newby's loan would not be extended past mid-January 2009. Despite him not having played in the last two games, Newby's loan was extended until the end of January, when the situation will be re-assessed. Despite limited first team appearances under the new manager,
Roy McFarland has stated that he is pleased with what he has seen of Newby in training and has signed him until the end of the season. Newby won the first senior medal of his career as Burton Albion won the
Conference National despite defeat to Torquay United on 26 April 2009. He was released after the end of the 2008–2009 season, as confirmed by
Davie Irons on 8 May in the
Greenock Telegraph. After his release from Morton, Newby signed for
Conference North club
Northwich Victoria in July 2009. He signed for
Colwyn Bay in the close season in time to start the 2010-11 campaign of
Northern Premier League Premier Division, helping them secure promotion to the Conference North. On 1 November 2011, he was appointed player-manager following the sudden departure of manager David Challinor to
AFC Fylde. And on 1 January 2013 Jon Newby was later sacked as manager of
Colwyn Bay after their 4–2 loss to
Vauxhall Motors. In January 2013 he was signed by
Warrington Town. Since 2014, he has been working with the
Liverpool F.C. Academy, first with the under-9 and under-12 age groups before becoming head of the under-11s in 2017; he is now part of the club's
scouting network. ==Honours==
