If you limit your MMA viewing habits to only UFC content, then you haven’t see any of Conor McGregor’s bouts, before he joined the world’s biggest, MMA promotion.

Yes, before McGregor signed with the UFC, the Irish fighter generated a ton of buzz overseas, by winning Cage Warriors featherweight and lightweight titles. In the video below, you’ll witness McGregor knocking out Ivan Buchinger to become the promotion’s 155 champ. At the time, it was McGregor’s eighth straight win.

Up next, as you surely know, McGregor will box Floyd Mayweather on August 26th.
