With Labor Day upon us, the summer season is truly coming to a close. Certainly that was evident last night with NFL preseason preemptions on some NBC and CBS affiliates and the Season 3 finale of The Night Shift (1.2/5).

No word if the medical drama will be back for a fourth season, but all the cliffhangers were dangling on Wednesday to set up the show if NBC grants one. Based on ratings, there might be a good case for such a renewal; Night Shift went up a tenth from last week to not only match a season high among adults 18-49, but also match its Season 2 finale. That May 18, 2015 episode was on a Monday and had a pretty strong episode of The Voice as a lead-in.

In fact, with a steady America’s Got Talent (2.1/8), last night’s Night Shift was up a touch in viewers to 5.80 million from the 5.20 million it had in May last year. Back then it faced an original NCIS: LA as opposed to the weaker American Gothic (0.5/2), which was up two tenths itself from August 24.

All of which means NBC won Wednesday night with a 1.5/6 rating and 7.84 million viewers.

Although American Gothic delivered a rise for CBS, heavyweight Big Brother (1.8/7) took a 14% hit from last week’s season high – though it might see adjustments later today. On the ratings flip side, Fox’s MasterChef (1.4/5) was up a tenth from its August 24 episode. The CW’s Penn & Teller: Fool Us (0.5/2) and Whose Line Is It Anyway? (0.4/1) were up 25% and flat, respectively.

ABC was all encores last night. And remember, there’s no preseason NFL on nationally tonight.
