Kayne McLaggon is a Welsh attacker who began his career with Southampton. He signed professional terms with Saints in September 2007 and made his first team on Boxing Day 2008 at Plymouth. Two days later McLaggon set up David McGoldrick's goal in a 1-1 draw against Reading. McLaggon made a great impact after coming on as a substitute for the injured Lee Holmes at Norwich on 27th January 2009, scoring Saints first in a 2-2 draw and causing the Canaries defence all sorts of problems throughout. McLaggon's final appearance of the season (and final appearance for the club) came on Valentine's Day 2009 as a sub at Bristol City. He played 8 times for the St Marys club in total, before injury cut his 2008/09 season short.
McLaggon joined Blue Square Premier outfit Eastbourne Borough on 11th November 2009 on a month's loan. The winger scored one goal in three matches for The Sports. He was released by Southampton on 15th May 2010. On 4th August 2010, Kayne joined Salisbury City. He helped the club win promotion back to the Conference South, and formed a good partnership up front with Jake Reid. McLaggon scored a number of key goals in a successful first season with the Wiltshire club.
In July 2011 McLaggon signed a one year deal with League Two side Bristol Rovers.
