A leap of faith.
There's no other way to describe Joe Duffy's return to mixed martial arts.
The Donegal lightweight has had a perfect comeback to the cage since he took time off to try his hand at professional boxing, where he went 7-0 with two knockouts.
But now it's the octagon where Duffy is plying his trade and he's finished both of his opponents in the first round since being handed his UFC debut earlier this year.

The headliner of UFC Dublin has moved his training to Montreal's Tristar gym in a bid to pave a path to UFC gold and the On The Fly video series shows the commitment that "Irish Joe" has put in to his career.
Training with Firas Zahabi, the maestro who guided the career of the legendary Georges St-Pierre, looks as exhausting as it is fulfilling as Duffy goes through the very trying Shark Tank training system.
Watch as the last man to beat Conor McGregor (the obligatory mention) guides you through his crazy sparring and glum dormitory to prove that the life of a fighter isn't for the weak of heart.
