"Game of Thrones" showrunners David Benioff and Dan Weiss are serious UFC fans -- a while back they told the UFC Unfiltered podcast they spend more time talking to the GoT cast about UFC than the HBO show. That love seems to have spilled onto the HBO show for Season 7.

Reports recently came out that Ultimate Fighting Championship mixed martial artist Conor McGregor would be joining Season 7, which is now filming in Northern Ireland. First a rumor, McGregor's involvement was confirmed by UFC president Dana White, who told Fox Sports Live (via TMZ), "I knew that a few months ago that they were interested in putting him in the show. And I'm glad he did it. It'll be great."According to Watchers on the Wall, the role is a non-speaking cameo. Here's their report:

A WotW source tells us that Conor McGregor will be playing a pirate belonging to Euron Greyjoy's crew, on the ship Silence. The part is a fairly small one, a cameo, so fans who are worried about his acting ability, don't sweat it. There is no speaking involved with this part, and it's definitely a short-term gig.

Good. The last thing GoT needs is to distract fans with celebrity cameos just because The Powers That Be happen to be fanboys. McGregor will probably fit in enough that seeing him won't take us right out of the story. That's the hope, anyway.

"Game of Thrones" Season 7 premieres in summer 2017.
