Sure they can, just depends if the owner is willing to spend cash or not. Cowboys would let them go, eagles would keep both, just depends on ownership.
https://www.nbcsports.com/nfl/profo...exans-jaguars-game-at-londons-wembley-stadium The NFL likes to boast about its growing popularity overseas, but there’s at least one sign that foreign fans are deciding NFL tickets aren’t worth the price. Tickets to the October 18 Texans-Jaguars game at London’s Wembley Stadium are not selling well. General tickets have been on sale since May 29, and it remains easy on ticket sites to find large blocks of tickets available. Searching ticket sites, fans can find blocks of 12 seats together in many sections of the stadium. The popular NFL UK Tickets social media account, which tracks ticket availability for NFL London games and is not affiliated with the league, posted a seating map showing many tickets remain unsold. “Can’t actually believe how badly the Texans v Jaguars game has sold. Over a week of the general sale and this is a snap shot of what the stadium looks like. Gone are the days of selling out the first day, people voting with their feet and staying away due to price,” NFL UK Tickets posted.
