Date of birth
The Scottish centre half arrived at Oakwell in the summer of 2017, joining the Reds from Partick Thistle after a superb 2016/17 season in Scotland where he was outstanding and ultimately named in the SPL Team of the Year.
Standing well over six feet tall, the dominant young defender was handed a three-year contract by the Reds having signed for an undisclosed fee.
The 21-year-old was hoping to continue his rapid climb in professional football with the Reds, and he made an impressive beginning to his Barnsley career, earning many plaudits in the first half of the 2017/18 campaign, and was eventually voted Players' Player of the Year.
With the Reds relegated in his debut season, Lindsay was then part of the squad who were immediately promoted the following campaign finishing 2nd in League One.
Lindsay is under contract with Barnsley until the summer of 2020.
