Medics working for sports bodies including the Scottish Football Association, Scottish Rugby Union and FIFA have signed up to ScribePro, which records medical interactions in real-time.

It was created by the first team doctor of the Scottish men's national football team Jonny Gordon and David Lowe, together with healthcare specialists familiar with technology.

ScribePro launched commercially in 2021, and it is hoped that its FirstAid and Event apps can be added to its Teams system.

MacKay and his wife Jackie believe that the app holds significant value for sports teams, with his investment aimed at accelerating ScribePro's entry into the market, furthering its product development and research and developing its international reach.

"When I was a footballer, I realised the insecurity of injury and just how devastating it can be," he reflected.

"Simple problems can become a serious disability if they’re not addressed or identified at the appropriate time.

"I was also very aware of the lack of continuity or recording or evidence-based advice for players, not just in the footballing world, but in other sports and other disciplines.

"So when I heard about ScribePro and about what Jonny was trying to do in the world of sports medicine, I immediately saw the potential and the importance of this.

"I have a lot of confidence in Jonny’s clinical ability and when he explained the vision for ScribePro, I was very keen to do whatever I could to support their venture.

"The vision is also very timely - sport is looking for someone to take the lead in this field and provide something that allows medical information to travel with the player, to ensure that continuity.

"If medics have instant access to that information, it can dramatically improve the outcome for those involved in sport and ScribePro is really going to address this very successfully.

"I wouldn’t be at all surprised if in due course it becomes the norm that clubs and associations expect people to be able to provide that kind of information and I believe ScribePro is clearly going to lead in this area of sports medicine."

Mackay played for Scottish giants Rangers at reserve team level, but switched his focus to medicine after his playing career ended due to serious ligament damage in 1990.

He has since worked with Scotland's rugby team and Premier League football clubs, and as a doctor at the Glasgow 2014 Commonwealth Games.

He now heads up a sports injuries clinic.

ScribePro has targeted generating revenues of £4.5 million ($5.5 million/€5.1 million) by 2025.
