1) “Scrubs” return, 8 and 8:32 p.m., ABC, rerunning at 9:58 and 10:31. After a nine-year run, this show ended in 2010 …. Except now, 16 years later, it’s back. J.D. (Zach Braff) returns to the hospital and finds that his old colleagues are still there. Donald Faison and Judy Reyes (shown here with Braff) plus Sarah Chalke, Neil Flynn and John C. McGinley are all back.
2) “The Greatest Average American” debut, 9:02 p.m., ABC. Nate Bergatze hosts a concept he co-created: Regular folks — not your “Jeopardy” masterminds — face odd challenges and trivia. A winner then competes for the average American annual pay, $67,920.
3) “Survivor” opener, 8-11 p.m., CBS. The 50th edition starts with 24 past contestants, ranging from the first (Jenna Lewis-Dougherty) and second (Colby Donaldson) seasons to the 49th (Rizo Velovic, Savannah Louie).
They reflect on their post-“Survivor” lives and compete anew — including an early injury that requires a switch in strategy.
4) “Nova,” 9 p.m., PBS. In Turkey, archaeologists probe remains that could change our view of history. They suggest an organized place for hunter-gatherers, 11,000 years ago — a time that was assumed to have only nomads. This follows an excellent “Nature” look at animal parenthood in jungles.
5) “Chicago P.D.,” 10 p.m., NBC. Here’s a rerun of the season-opener, a strong and propulsive hour. With his unit disbanded, Voight is working for Rapid Response; then he sees a chance to get his people together — with a terrific addition. This follows an 8 p.m. rerun of the “Voice” season-opener.
