Nicknamed 'The Silver Fox' by teammates due to his grey hair, McNaughton is a versatile player who can play anywhere on defence, including a more defensive minded midfield role. He began his career in the Scottish Premier League playing for the Aberdeen for six years.
After coming through the club's youth programme, McNaughton was thrust into the first team at 18, making his debut on 5 October in a 2–1 win over St. Mirren, and became a regular for the 2000–01 and 2001–02 seasons in a team containing lots of young players brought through the youth system like Darren Mackie, Russell Anderson and Darren Young. A knee injury sustained in 2002 kept him out for 12 weeks and on his return McNaughton struggled to return to form. It wasn't until new Aberdeen manager Jimmy Calderwood arrived, that he managed to recover his previous form.
During the 2005–06 season, McNaughton was linked with moves to Celtic and Fulham, but nothing came of either and he remained at Pittodrie.
On 26th May 2006, it was announced that he would be joining Football League Championship side Cardiff City on a free transfer. McNaughton quickly became an important part of manager Dave Jones's plans as he played in the left full-back position, and his form once again earned him a recall to the Scottish national team, although injury robbed him of the chance to take his place in the squad. During his second season at Cardiff, having switched to right-back, McNaughton played in all six matches of the club's run to the 2008 FA Cup Final, including scoring his first goal for the club on 27th January 2008 with a 20-yard volley in a 2–1 victory over Hereford United in the fourth round. His first league goal came just a few months later when he scored on the final day of the season against Barnsley in a 3–0 win.
The start of the 2008–09 season saw McNaughton his 100th appearance for the club when he played against Watford on 21st October.
During a pre-season friendly against Celtic on 22nd July 2009 he suffered an ankle injury which kept him out for the opening two months of the season. After appearing for the club's reserve side, he returned to the first team on 17th October 2009 as an unused substitute during a 1–1 draw with Crystal Palace but suffered a recurrence of the injury kept him out until 17th November 2009 when he played 45 minutes of a reserve team game against Hereford United. He returned to the line-up on 21st November 2009 against Barnsley, but was taken off in the 21st minute for Paul Quinn with a back injury. On 23rd November McNaughton was sent to have a scan on the back injury, which the club's medical staff believed to have caused the problem and resulted in him being out for two weeks. On 5th December 2009 McNaughton played his first 90 minutes of the season in a 1–0 win over Preston North End. The next season his injury worries ceded and he has played in every league up to and including the game against Barnsley. McNaughton was Cardiff's most consistent defender throughout the 2010–11 season, and won the Player of the Year award.
On 2nd May 2011, McNaughton was involved in an incident where he collided with assistant referee Sian Massey.
In 2011/12, McNaughton was named as stand-in captain in Mark Hudson's absence starting on 22 November against Coventry City. He went onto make three further appearances as captain, during which time he made his two hundredth league appearance for Cardiff in a 1–0 win over Nottingham Forest on 26th November 2011. He also played a part in the club's League Cup run to their first ever final, which they lost 3–2 on penalties to Liverpool.
McNaughton's four-hundredth league appearance for Cardiff came in a goalless draw at Brighton & Hove Albion on 21 August 2012. McNaughton started over half of City's fixtures in 2012–13, as Cardiff finally achieved promotion to the Premier League. With his contract expiring during the close-season, the club has confirmed that McNaughton has been offered a new deal. On July 5, 2013, it was announced on the official Cardiff City website that McNaughton had signed a new one year contract extension with the Bluebirds.
On 27th September 2013, McNaughton joined Bolton on a 28-day emergency loan deal. He made his first appearance for Wanderers four days later in a goalless draw with local rivals Blackpool at Bloomfield Road. After becoming the club's first choice right-back during his stay with Bolton, he scored his first goal for the club in the 1-1 draw with Charlton Athletic on 21st December 2013, this was his first goal in the League since scoring for Cardiff against Barnsley in May 2008
McNaughton returned to Cardiff after his loan spell and on 7th March 2014, McNaughton signed a new one-year extenstion with the Bluebirds.
McNaughton was currently the Cardiff's longest-serving player and a huge fan favourite, known to the fans as 'super Kev' but as you know he's with us for the remainder of his contract.
Welcome back Kevin and here's hoping you have a fantastic season (and more!) with us.
