President Trump reportedly will take in an MMA bout Saturday night at Madison Square Garden — and stay in the city into Marathon Sunday, potentially putting Midtown traffic into a chokehold.

Trump will be in attendance when the Mecca plays host to UFC 244, headlined by a five-round tangle between welterweights Nate Diaz and Jorge Masvidal, a New York Times reporter tweeted on Tuesday, citing sources.

In 2016, the then-president-elect was invited by UFC president Dana White to a fight at the Garden, but ultimately decided not to go on the advice of his Secret Service handlers.

Following the contest, Trump reportedly will crash at Trump Tower into Sunday — when the New York City Marathon was already set to snarl traffic across the Big Apple.
