TMZ Sports: Is Jon Jones training for an upcoming fight?

We have no idea when, or if, Jon Jones will fight in the Octagon again.

But that’s not stopping the former champion from getting into shape.

Check out this video via TMZ Sports of Jones training recently, insisting ‘if I made it to the top of the mountain once, I can do it again.’

Jones defeated Daniel Cormier for the UFC Light Heavyweight title back in July, only to have the title stripped after it was discovered Jones, again, tested positive for a banned substance.
