The games will be played at Tottenham Hotspur Stadium, Kaplan adds.
The NFL is set to return to London for two contests this season. It will be the first time teams play overseas since 2019. There have been 28 games held in London since the series began in 2007.
However, the league won't host a game in Mexico City this year due to the pandemic, Kaplan notes.
The number of international games will expand to four per season beginning in 2022.
The official 2021 NFL schedule is set to be released Wednesday at 8 p.m. ET.
