1) “Celebrity Weakest Link” debut, 9 p.m., Fox. Celebrity versions may work for some games, but not this one. “Weakest Link” is a dog-eat-dog game, based on dumping the others and getting the money. It doesn’t work with friends playing for charity. (Tonight has former “Glee” co-stars including, shown here, Jenna Ushkowitz and Amber Riley.) Jane Lynch adds quips, but it feels forced, a variation on her “Glee” character.
2) “Name That Tune” season-opener, 8 p.m., Fox. Most shows will wait another week or so, but this one and “Link” get the fall season started. Jane Krakowski is back as host, with Randy Jackson leading the band.
3) “Opry 100,” 8-11 p.m., NBC. This reruns the March celebration, marking 100 years of the Grand Ole Opry. It has longtime stars — Blake Shelton (who hosts), Garth Brooks, Reba McEntire, Carrie Underwood, Clint Black, Alan Jackson. Keith Urban, Vince Gill, Dierks Bentley — plus Kelsea Ballerini, Luke Combs, Lainey Wilson, Carly Pearce and more.
4) “Celebrations with Lacey Chabert,” 8 and 9 p.m., Hallmark. The shows that launched Hallmark+ last year are gradually moving to this channel. The “Groomsmen” trilogy is Saturdays (concluding this week), “Chicken Sisters” is Sundays and here’s this reality show. Chabert (from “Party of Five” and many Hallmark movies) hosts events for worthy souls.
5) MORE: Football starts early, with the Bucs-Texans at 7 p.m. ET on ABC and ESPN. That leaves time for the Chargers-Raiders game, at 10 on ESPN. Also, the dark comedy “Dr. Strangelove” is 8 p.m. ET on Turner Classic Movies. At 10, PBS’ “POV” views an environmental disaster in Siberia.
