WEEI’s MIA morning man John Dennis is scheduled to return to the airwaves Monday and his boss says he expects him back, but word from our station spies is that the longtime jock talker actually quit his gig two weeks ago because he has had it with on-air partner Kirk Minihane.

Entercom Boston boss Phil Zachary told the Track yesterday that “Dino is happily enjoying his vacation” and that he is “scheduled to be back next week.”

But station sources say Dennis has made it clear he will not return and all that’s left to ?negotiate is the terms of his departure.

“(He’s) all done ?doing sports talk in Boston. Twenty years. Dino out,” said our spy.

As for the ongoing negotiations, the station source said, “It is something that will probably percolate quickly, or it will get ugly really fast.”

Word is, Zachary would like Dennis to say he took “early retirement” — his contract still has another year on it — and that he would return to do special events like the annual Jimmy Fund Telethon.

Dennis reportedly is willing to go that route — if Entercom makes it worth his while. If they don’t, Dennis could get into a rather nasty spat with his former on-air partners, neither of whom are reportedly sad to see him go.

Relations among the three have been deteriorating for more than a year. While Gerry Callahan and Minihane get along, Dennis has complained on the air that the two have frozen him out. Minihane — who Forbes called “the most acerbic man in sports talk” — in particular gets under Dennis’ skin.

Word is, ’EEI’s rivals at 98.5 The Sports Hub are watching the drama carefully, because if things go south they can use the morning show chaos in their pitches to advertising clients.

Zachary previously told us he hopes to hang onto Dennis for another year.

“Dino is under contract through next September (2017) and speaks of retirement incessantly,” Zachary said. “My goal is to get him to next September, but the call of the beach is a persuasive one. Dino’s on vacation. … Hopefully, that suffices.”

But we’re told Dino’s “vacation” was actually more of a “cooling off period” after he handed in his resignation. He didn’t return a call yesterday but suffice it to say, his desire to retire hasn’t cooled.

Zachary shot down a suggestion that Dennis could return to the station on a different time slot where he wouldn’t have to work side-by-side with Callahan and Minihane.

“There are no plans for him to be on any other show, Zachary said. “That has never been discussed.”

As always, do stay tuned …
