The New York Jets have sent 350 rolls of toilet paper to London ahead of their match against the Miami Dolphins on Sunday, supposedly to replace the "thinner version used in England".
Whenever an NFL team plays abroad, much effort is made to recreate the routine and home comforts the team are accustomed to.
The trip has been meticulously planned since it was announced, the New York Times reports.
The Jets' flew in the chef from their London hotel so they could learn how food for the players would be prepared at the team headquarters.
American home comforts like hot sauce and barbeque sauce have also been sent over.
Players were advised about the cultural and culinary differences between the US and the UK, and warned about the higher voltage of Britain's plugs.
“Some may say that’s a little over the top or whatnot, but it didn’t really cost that much, so why not?” Aaron Degerness, the Jets' senior manager of team operations, told the New York Times. “We’re basically trying to replicate everything that we’re doing here over there.”
The New York Times sports reporter Ben Shpigel, who wrote the article about the logistics of bringing the team to the UK, told the BBC the Jets' relied on the advice of an intern who had been to London several times.
"He noticed while he was there that - and I quote - 'the toilet paper was very thin because their plumbing isn't as good'.
"So, the intern informed the operations staff and the Jets ordered 350 rolls of toilet paper for the hotel and the stadium."
The New York Jets will play the Miami Dolphins at Wembley Stadium from 2.30pm on Sunday.
