Jets owner Woody Johnson is in Arizona for the NFL owners meetings, along with his brother Christopher, according to Kimberly A. Martin of Newsday.
The Jets owner declined to talk to reporters on Sunday.
Woody Johnson has long been expected to be named the ambassador to the United Kingdom in President Donald Trump's administration, although the president has not yet formally announced the appointment.
In January, Trump referred to the Jets owner as "the ambassador Woody, going to Saint James."
While Woody is expected to retain ownership of the Jets, Christopher is expected to assume control over the day-to-day operations of the team.
