The Steelers' preparations for their game in Dublin went awry after one of their players was reportedly 'jumped and robbed' earlier this week.
Pittsburgh is taking on the Vikings at Dublin's Croke Park as part of the NFL's international series, which will see a record seven games staged abroad this season.
But backup quarterback Skylar Thompson was left with minor injuries after being the victim of a robbery on Friday night, NFL Network's Tom Pelissero said.
Thompson, who was already on IR with a hamstring injury, is said to be OK following the ordeal.
Steelers Spokesman Burt Lauten said in a statement: 'We are aware of a situation involving Skylar Thompson on Friday night in Dublin. We will have no further comment at this time as we are working with NFL security to gather more information regarding the incident.'
Thompson was seen arriving to the Steelers' game early on Sunday and did not have any noticeable injuries on his face.

The incident follows the Chiefs and Chargers' season-opening matchup in Sao Paulo on September 5, which appeared to take place without any hiccups.
In 2018, four Jaguars players were arrested while in London for a game after being accused of not paying a $64,000 bar tab. The charges were dropped after the bill was paid.
