McCallum, known by his performance name of "Lionheart", had competed for WWE and TNA during his career.
A day before his death, the ICW Insane Championship Wrestling world heavyweight champion posted on his Twitter account: “One day you will eat your last meal, You will smell your last flower, you will hug your friend for the last time.
"You might not know it's the last time, that's why you must do everything you love with passion” #Afterlife @rickygervais."
On Thursday it was announced that McCallum was dead.

Pete Dunne, the longest-reigning WWE UK champion, tweeted: "I always looked up to Lionheart's professional approach to wrestling when it was far from that at the time.
"People like him were pivotal in the growth of a scene that has lead to so many people being able to do this for a living."
British wrestler Will Ospreay, who currently competes in Japan, said: "Every time I've met you, you have been nothing but a sweetheart. I honestly cannot believe I'm writing this tweet.
"Devastated doesn't cover how I feel."
