Douglas was nominated for the challenge on Twitter, with blizzards and subzero temperatures hitting Scotland throughout the afternoon.
And he did so in style… wearing just his goalkeeping gloves and a pair of shorts.
The former Scotland international, who won three league titles and three Scottish Cups while at Celtic, revealed the details of the challenge in the video posted to his Twitter account.
Douglas confirms that he was nominated to either donate £20 to the Beatson Cancer Charity or create a snow angel… and he was more than happy to do both!:

Hats off, that is a brilliant effort from the 45-year-old!
Here’s hoping Douglas’ former Hoops team-mates Sutton, Hartson and Petrov all see the Tweet and get involved!
Rab also provided a link to his JustGiving page, with all proceeds going to the charity.
