Irish scrapper Conor McGregor is the gift that keeps on giving. Without even having defeated UFC 189 main event opponent Chad Mendes yet, he’s already begun planting the seeds of beef that could turn into another eagerly-anticipated fight.

The scene: Backstage at the weigh-ins yesterday, in the bowels of the MGM Grand. The cast: McGregor, Urijah Faber, and a couple hangers-on.

The action: A tussle! It isn’t much, but it’s certainly a foundation for future ill will.
