Derek Jeter busted a gut over The Post’s back page last week that appeared to show the Yankees captain having put on a few pounds.

On Monday, Jeter went on ESPN Radio and joked about The Post’s back page from Nov. 30 with him carrying some extra weight as he rehabbed from ankle surgery.

The headline was “Derek Eater.”

“I thought it was pretty funny,” Jeter said. “I guess there’s a lot of things you can do with a picture. The funny thing is we were just talking about, before then, the day or two before then, people were telling me I lost a lot of weight, and then two days later I’m on the front page of the New York Post. They had a little fun with it. But it’s over and done with.

“Hey listen, I’m not battling the New York Post,” Jeter continued. “That’s a no-win situation. I guess they do what they do, they had fun with it. I got messages with a lot of different people asking me what I’m doing.”

Good news for Yankees’ fans is that Jeter said he plans to be ready for the season opener on April 1. The 38-year-old broke his left ankle in Game 1 of the American League Championship Series against the Tigers and soon thereafter had surgery. The Tigers swept the series, and then got swept in the World Series by the Giants.

“Yea, no question,” Jeter said about being ready for the season opener. “ I’m in a walking boot now for another few weeks, then I’ll be good to go. It’s been 6-7 weeks where I haven’t been able to move too much. It’s been healing as expected. We’ve still got a long way to go before the season starts, but I’ll be ready.”
