A selective critical checklist of notable Tuesday TV:

America’s Got Talent (8/7c, NBC): The show must go on, but as the summer’s top-rated talent competition heads into its live shows at Universal Studios Hollywood, the production encountered another setback with judge Simon Cowell‘s injury over the weekend. Still recovering from back surgery, Cowell will reportedly miss this week’s first two live episodes‑a performance show followed by a results show on Wednesday (8/7c) — but judges Heidi Klum, Howie Mandel, Sofia Vergara and host Terry Crews will be on hand to welcome back 11 of the top 44 acts, including several introduced online during remote auditions. Also returning for the first live show: Golden Buzzer recipient Roberta Battaglia, the 10-year-old Canadian vocal powerhouse. Five will make it through to the semifinals, and on Wednesday, fans have the opportunity to save one of their favorites.

Finales: The well-regarded superhero adventure DC’s Stargirl (8/7c) wraps its first season — it has been renewed — with Courtney (Brec Bassinger) and her Justice Society of America crew facing off against Icicle (Neil Jackson) and the Injustice Society… OWN’s sudsy Greenleaf (9/8c) says one last hallelujah before closing shop for good, with Grace (Merle Dandridge), Lady Mae (Lynn Whitfield) and the rest of the family trying to make peace with their stormy past as they look to the future. Followed by Greenleaf: The Homegoing Celebration (10/9c), an emotional behind-the-scenes farewell that looks back at the series while the cast prepares their goodbyes.
