To twist a theme song a little: Michael Kay is not on the radio today …

Kay’s status has been the sports radio story of the summer. The explanation that Kay was on vacation was out there, but not believed, creating a vacuum for conspiracy theories.

Kay has heard them all. He had a “nervous breakdown.” There was a “contract snafu.” He was “secretly fired” or “retired.”

None of those are true. After 10 weeks off, Kay will return to “The Michael Kay Show” on the day after Labor Day, Sept. 6, to join Don La Greca and Peter Rosenberg as the main host of his program.

Though Kay is coming back, it is fair to ask if it is the beginning of the end of his time on New York sports radio afternoons. Kay had the classic battle with Mike Francesa for afternoons, finally beating WFAN on Francesa’s way out. He and his crew have now gone back-and-forth with Craig Carton and Evan Roberts, but C&R, for a second book in a row, knocked off Kay’s show in the spring. At 61, after two decades, will Kay be on the radio on Sept. 6, 2023?

Maybe. Maybe not.

His ESPN contract will be up in September of next year. Though it’s possible he could stick around a few more years, this is how these things work: You start taking summers off, then you take a little more time off or you hang up your mic. (Sometimes, you are “begged” to return, of course.)

Asked directly if this could be it, Kay didn’t say yes, but he acknowledged decisions are on the horizon.

“I don’t think so,” Kay told The Post. “At some point, I’m going to have to make a decision as I get older, but, at this point, full-speed ahead.”

Though “The Michael Kay Show” has repeatedly said he was simply on vacation, ESPN hadn’t given a date of return until this week, when it said it would be Sept. 6. Kay took the full summer off because the summer ratings book is deemed unimportant.

Still, it is a stark contrast from Carton, who has taken one full week off and a few three-day weekends. He and Roberts came off vacation heading into the Subway Series last month.

Kay originally asked to take 12 weeks off, but ESPN asked him to return in early September with baseball heating up and the NFL starting in earnest.

“To me, it was laughable to see all the conspiracy theories,” Kay said. “ ‘There was a contract snafu.’ Or, ‘There was a suspension,’ or ‘I was retiring and they just weren’t saying anything.’ I read on social media that I had a nervous breakdown. Funny, I had a nervous breakdown, but I was still able to do the Yankee games.

“The only reason, at 61 years old, it is tough to do both of them. It is tough to do both of them throughout the whole baseball season, so I figured I’d do the first three months of the season doing both, and the summer book — they say in radio — is not an important book. Jimmy Kimmel does it. Howard Stern does it. Nobody has put conspiracy theories to them. I essentially took the summer off. It was a vacation.

“The funniest thing to me was people thought there was something wrong with me. Did they think there was a hologram doing the Yankee games? All they had to do was turn on the Yankee games and I was right there. So how could they think there was anything wrong with me? People’s imaginations, God Bless them, I’m thrilled that they actually noticed I was gone.”

They did. It is fair to wonder when Kay steps aside for good.

Amazon Prime Video will stream its first exclusive “Thursday Night Football” game when the 49ers face the Texans in a preseason matchup this week. This is the soft launch of Amazon’s new billion-dollar-plus per year deal with the NFL to stream “Thursday Night Football.” To watch the games, you will need an Amazon account, much as Yankees fans needed to view 21 games this year. The difference for the NFL games is that they will be available nationally, while the Yankees’ games can only be accessed by Prime members locally.

The crew for Amazon features Al Michaels, Kirk Herbstreit and sideline reporter Kaylee Hartung.

“Even though it’s a different platform, the one thing you can count on is that we are not going to reinvent the wheel,” Michaels said.

Papa Clicker cannot believe that 50 years have passed since the Miami Dolphins’ perfect season, which has been documented in Marshall Jon Fisher’s book, “Seventeen and Oh: Miami, 1972, and the NFL’s Only Perfect Season.” The is a nice way to reminisce and bring in the upcoming NFL season. It doesn’t get a perfect score, but a 4.25/5 clickers is pretty good.
