1) Football. So far, the pro play-offs have been short of surprises. Now the two conference leaders – each with a 15-3 record – host championship games, with the winners going to the Super Bowl two weeks later. At 3 p.m. ET on Fox, the Philadelphia Eagles host the San Francisco 49ers (15-4); at 6:30 on CBS, the Kansas City Chiefs host the Cincinnati Bengals (shown here, 14-4).
2) “Fire Country,” after football (about 10 p.m. ET), CBS. A top-10 ratings hit in its first season, this show now gets a shot at the big football viewership. Tonight, a plane crash ignites a monstrous fire; the prison-inmate firefighters link with a civilian crew.
3) “Miss Scarlet and the Duke,” 8 p.m., PBS. For the second straight week, Miss Scarlet is Duke-less. Last week, she had an out-of-town adventure; now she’s back, but he’s gone. A rougher, maybe-corrupt chap is in charge, leaving her with no police support. It’s a good episode, with a brief glimpse of “the Duke” in the final moments. And it leads into an entertaining “All Creatures Great and Small,” complete with a 1940s-style car chase.
4) “Sing” (2016), 7-9 p.m., NBC. Even the broadcast networks, which usually avoid movies, are trying them tonight. NBC has animated fun, with animals in a music contest; from 8-11 p.m., ABC has “The Avengers” (2012), stuffed with Marvel superheroes. Cable adds more superheroes: HBO has DC’s “The Batman” (2022) at 5:52 p.m.; TNT has Marvel’s “Thor: Ragnarok” (2017) and “The Avengers: Endgame” (2019) at 7 and 9:45 p.m.
5) ALSO: There’s more competition, including the men’s figure-skating finals, from 3-6 p.m. on NBC. Others are reruns: Fox has the final five chefs on “Hell’s Kitchen” at 7 p.m. and the start of “Special Forces: World’s Toughest Test” at 8 and 9; NBC has “America’s Got Talent: All-Stars,” from 9-11 p.m.
