What a difference a week makes.

After saying goodbye to the low-rated new season of The Celebrity Apprentice, NBC got a boost from its (temporary) time slot replacement. A two-hour American Ninja Warrior: All Stars special drew a 1.4 rating among adults 18-49 — besting Celebrity Apprentice's entire run with new host Arnold Schwarzenegger, which wrapped the most recent season with a 0.9 rating.

With the help of a stronger lead-in, Timeless rose two-tenths for its first-season finale (0.9 adults).

ABC was once again victorious thanks to The Bachelor (2.5 adults), which was followed by an even showing of Quantico (0.7 adults).

CBS was flat across the board, save for Superior Donuts, which dropped two-tenths to a 1.2 rating.

Fox saw dips for both 24: Legacy (1.1 adults) and APB (0.8 adults), which fell two-tenths and three-tenths, respectively.

Supergirl (0.7 adults) and Jane the Virgin (0.5 adults) were both steady for The CW.
