Shearer was born in
Coylton in
South Ayrshire and started his football career in
Scottish Junior Football with
Trabboch before being invited for a trial at
Southampton in the summer of 1908. He showed "
considerable promise" in the trial matches and was rewarded with a professional contract. He made his debut for the "Saints" in the opening match of the 1908–09
Southern League season, a 3–1 draw at
Brighton, but after four appearances, he lost his place to
Frank Jordan in mid-September. Described as "
naturally skillful", Shearer was able to keep the ball close to his feet and as a result incurred regular kicks and bruises to his ankles, but his individuality was never properly exploited by his team-mates. In the summer of 1909, Saints signed
Sam Brittleton who took over at inside-left, before losing out in turn to
Bob Carter. Shearer was then third-choice for the inside-left berth, and it was only in the last month of the season that he made a sustained run in the side with five
first-team appearances. He returned to Scotland in the summer of 1910 to join
Nithsdale Wanderers of
Dumfries, before returning to England with
Bradford Park Avenue in December 1912. After making only one league appearance for Bradford, Shearer retired in 1913, then immigrating to America. ==References==
