Former WWE Champion turned actor Dwayne “The Rock” Johnson took to his official Twitter account to pay tribute to the late Adrian “Lionheart” McCallum, the World Champion of Scotland’s Insane Championship Wrestling promotion, who tragically passed away earlier in the week at the age of 36.

The Rock noted that he never had the opportunity to shake McCallum’s hand, but was sending his family, friends and the UK wrestling community his love, support and strength.

The GoFundMe campaign to assist McCallum’s funeral expenses has doubled its £6,000 goal and currently sits at £14,369 at the time of this post. You can donate at this link.
