The 2016 NFL regular season is on the horizon and Arizona Cardinals cornerback Patrick Peterson appears to be in peak form already.

Peterson hung out with Carrie Underwood as the duo filmed promotional material for NBC's "Sunday Night Football" on Tuesday.

Cardinals safety Tyrann Mathieu also took part in the promotional event, alongside Seahawks stars Kam Chancellor, Earl Thomas, and Raiders edge rusher Khalil Mack.

In a potential Super Bowl LI preview, the Cardinals square off against the New England Patriots during the first Sunday night game of the season on Sept. 11.
