NFL Season officially begins its regular season with Dallas at Tampa Bay (NBC, 8:20 p.m.), also kicking off Thursday night football. Pregame festivities at 7 p.m. include Tampa Bay getting their Super Bowl rings, and a performance by Ed Sheeran. 

The eight-episode “Kin” (AMC+, streaming) is a decent Irish mob drama set in contemporary Dublin, with a strong cast that includes Aidan Gillen (“The Wire,” “Game of Thrones”), Charlie Cox (“Daredevil”), and Ciarán Hinds (“Game of Thrones,” “Rome”).

The most tasteless of the 20th anniversary commemorations must be the special “Long Island Medium: In Memory of 9/11” (TLC, 10 p.m.) in which film flam woman Thresa Caputo purports to chat with some of the those killed in the terrorist attacks. 

A much better alternative is “No Responders Left Behind” (Discovery+, streaming) about the work of Jon Stewart and 9/11 activists to secure health benefits for first responders to the attack.

And there’s a salute to first responders in the annual hockey matchup between New York firemen and police on “Hockey Heroes: FDNY vs. NYPD” (ESPN2, 8 p.m.).
