Is the Return of the Cannon a possibility at age 47??
HELL YEAH!!! So says Shannon Briggs himself, who tells TMZ Sports he'd be down to take a fight in 2020 ... all he needs is a few months to get back into shape.
We spoke with the 2-time world heavyweight champ about the upcoming rematch between Anthony Joshua and Andy Ruiz ... when Briggs started showing us he's still got it!!
Of course, Briggs hasn't fought since 2016 .
