1) “Saturday Night Live” season-opener, 11:29 p.m., NBC. As rumors swirled, fans feared the worst. Maybe Kate McKinnon was leaving … or Cecily Strong … or Kenan Thompson. But all three are back for this 47th season; only Beck Bennett and Lauen Holt are leaving. Bowen Young and Chloe Fineman move up to the main company, with three newcomers added. Owen Wilson (shown here) hosts the opener, with Kacey Musgraves as music guest.
2) “iHeart Radio Music Festival,” 8-10 p.m., CW; concluding Sunday. Each year, Ryan Seacrest hosts an upbeat, two-day concert in Las Vegas; then it’s edited into a two-night special. This year’s Vegas shows have some country (Darius Rucker, Sam Hunt, Gabby Barrett, Russell Dickerson, Florida Georgia Line), some long-time bands (Cheap Trick, Journey, Maroon 5, Weezer) and lots of newer stars – Billie Eilish, Khalid, Dua Lipa, Lil Baby, Olivia Rodrigo, Nelly, The Kid Laroi, Saweetie and more.
3) “La Brea,” 8 p.m., NBC. If you missed this debut episode Tuesday, catch it now. It’s not every day that you see a giant sinkhole appear, swallowing people, cars and buildings … or that you see those people plunge into an odd netherworld. We can’t guarantee this show will hold up – or that NBC won’t yank it early, as is its fashion – but it’s a splashy start.
4) “FBI International,” 8 p.m., CBS. Another Tuesday episode gets a quick rerun. This is the show’s second episode– and the first that doesn’t continue a story from the other “FBI” shows. An American kidnaps her son and takes him to Budapest … where he’s kidnapped from her. That’s followed by a “Magnum” rerun from April, with Magnum and Higgins taking care of an abandoned baby.
5) Sports rush. On the second-to-last night of the regular baseball season, Fox is hoping for a game (7:10 p.m. ET) that matters in the standings. As it happens, the top college football match-ups are earlier – Arkansas (ranked No. 8) at Georgia (No. 2) at noon ET on ESPN …. Cincinnati (No. 7) at Notre Dame (No. 9) at 2:30 p.m. NBC … and Mississippi (No. 12) at Alabama (No. 1) at 3:30 on CBS.
