Conor McGregor beats American Chad Mendes to win UFC title

Irish mixed martial arts fighter Conor McGregor was "overwhelmed" and "came to tears" after defeating Chad Mendes to win the Ultimate Fighting Championship interim featherweight title.

McGregor, 26, was dominated by his 30-year-old American rival and put on his back several times in Las Vegas.

But McGregor escaped a hold before a series of strikes gave him victory with three seconds left of the second round.
