Rich Walsh from WPXI interviewed Steelers president and co-owner Art Rooney II about the possibility of the Steelers playing a game overseas next year and it actually seems pretty close to being a real possibility. 

"Well, I think there's a chance we'll be playing overseas next year from what we hear. Whether it'll be Ireland or not, we haven't heard, I think it's a possibility but, they're still investigating what works. I think Notre Dame is playing a game over there in a few weeks and we'll see how that works"
