Background
Kerr was born in Rutherglen, South Lanarkshire, and attended Calderglen High School, in East Kilbride.
Kerr was born in Rutherglen, South Lanarkshire, and attended Calderglen High School, in East Kilbride.
A centre back, he has represented his country at levels from under-16 to under-21. Kerr began his professional career at Premier League side Birmingham City in 2011, having progressed through the club"s youth ranks. He never made an appearance for the club, and spent the 2012-2013 season on loan to Scottish Premier League side Motherwell, where he made 19 appearances.
He was released by Birmingham City in July 2013, having returned from his loan spell.
Kerr then moved to Motherwell on a permanent basis, making 40 league appearances in two seasons. He began his football career as a schoolboy with Motherwell.
Spotted playing for the Scotland under-16 team in the televised Victory Shield, he moved to England at the age of 16 to begin a two-year scholarship in Birmingham City"s youth academy. Much to his surprise, Kerr was included as defensive cover in the first-team squad for a 2010 pre-season tour to Hong Kong and China.
He signed his first professional contract, of two-and-a-half years, in January 2011.
Academy manager Terry Westley described the "tall and gangly" Kerr as having "good awareness on the ball", but said that it was "his change of pace that really convinced us to bring him here", comparing him with England international Matthew Upson at a similar age. He was part of the Birmingham squad for their 2011 pre-season visit to Ireland, and played the second half of the friendly against Cork City. Named in the "B" list for Birmingham"s 2011-2012 Europa League campaign, he was an unused substitute for the play-off second leg against Civil Defense Nacional.
In August 2012, Kerr rejoined Motherwell on a six-month loan after a successful trial.
The loan was later extended to last for the season. In April, Birmingham confirmed that his contract would not be renewed when it expired at the end of the season.
On 1 July 2013, after his Birmingham contract expired, Kerr signed a two-year permanent deal with Motherwell. On 31 May 2015, Kerr was involved in an incident in Fir Park following the result of a 3-0, 6-1 on aggregate, victory of Motherwell against Rangers, a match that secured Motherwell"s place in the Scottish Premiership.
After a clash between players Bilel Mohsni (Rangers), and Lee Erwin (Motherwell), Kerr proceeded to get involved to attack Mohsni.
Both team"s managers have described the event as both "unacceptable" and "disgraceful". Kerr was released by Motherwell at the end of the 2014/15 season. Kerr signed for Cowdenbeath in November 2015.
He made his debut for the Scotland under-16 team in August 2008 in a friendly match against a Jersey team, and played twice in that year"s Victory Shield.
The following year he made six appearances for Scotland"s under-17s, including two in the qualifying round of the 2010 European under-17 championships, and scored his first international goal, against Finland in the Nordic Tournament. As a 17-year-old, Kerr played two friendlies for Scotland at under-19 level in 2010, and appeared in five more matches in 2011, which included three European under-19 championships qualifiers.
Kerr made his under-21 debut in the Marbella Cup in October 2012.
