Former Miami Dolphins star Troy Stradford was fired from sports talk radio’s WMEN-AM (640) on Friday, a day after he was sent home in the middle of his show for questioning fellow host Sid Rosenberg’s professionalism.

Nearly four years after he was hired, the former running back received an email from James Crystal Radio Group’s VP, Steve Lapa, to let him know not to return to the Fort Lauderdale station for his 10 a.m.-noon show.

“I am surprised,” Stradford, 49, said about the firing. “I thought they just sent me home for the day [Thursday].”

Keith Sims, a former Fins offensive lineman, is set to take over the time slot Monday.

“My first call was to Troy,” Sims said. “I wanted to make sure he was OK with it. It’s a great opportunity.”

Stradford was yanked off the air during a commercial break Thursday morning when he and his listeners started criticizing the controversial Rosenberg, whose program airs before Stradford’s.

Rosenberg, who arrived at 640 two months after his firing from WQAM-AM (560) over a DUI arrest, had made a habit out of spilling over into Stradford’s broadcast time a la Howard Stern.

Usually, it was just a few minutes, but Thursday it ended up being an hour — and Stradford went off.

“Management is letting him, and that’s disrespectful to me and you [the listeners],” Stradford said on the air.

What’s next for Stradford?

“It’s not because I was in the NFL that I don’t need a job,” he said. “I’m looking for another radio job.”

Said Lapa: “Troy just let his emotions cloud his performance.”

Chef in peril

Charges pending against Jonathan Eismann in the killing of a pedestrian Wednesday morning in Miami could provide a stunning exclamation point on the fall from grace for a man who once ruled Miami Beach’s restaurant business.

Eismann is accused of killing a pedestrian at about 9 a.m. while allegedly driving away from the scene of another crash in which he was involved minutes earlier.

In the late 1980s and 1990s, however, Eismann could do no wrong — especially when it came to whipping up high-end food in a place where there wasn’t much of it.

“He became very important with places like Pacific Time,” said Larry Carrino, a restaurant publicist for more than 20 years. “You can call it iconic.”

Said longtime SoBe magazine publisher Jerry Powers: “Jonathan was among those who introduced a more sophisticated cuisine here. For a short time, he was the main man.”

But if Eismann was a great chef, Powers added, he wasn’t the kind of personality the Beach was looking for, and that began his downward slide.

“He’s not a warm-and-fuzzy guy, and that prevented him from going to the next level,” Powers said.

Besieged by creditors, according to records, Eismann turned away from the kitchen and became a Realtor earlier this year.

His financial situation started looking up, too. County records show he was able to stave off foreclosure on his home a month ago.

Calls to Eismann’s telephone went unaswered.
