FLORHAM PARK, N.J. — Brandon Marshall was Ryan Fitzpatrick’s go-to guy last season. And on Wednesday, he again came to his quarterback’s rescue.

In a race against time, Fitzpatrick drove his truck through the security entrance at the Jets’ facility and then hurried to make his way into the building. But there was just one problem.

“I didn’t have a door code,” Fitzpatrick said, smiling.

Seven months after ending the 2015 season with the Jets, Fitzpatrick no longer was one of them.

At least, not yet.

Just minutes earlier, agent Jimmy Sexton essentially had agreed to a one-year deal with the Jets, and Fitzpatrick was determined to be on time for the team’s 7 p.m. meeting.

“So I had to text Brandon and get his door code,” Fitzpatrick said. “Which I don’t know if he’s allowed to give it to me, but he did.”

Marshall had been waiting outside the building while his quarterback was en route to 1 Jets Drive. “He said I’ll be there at 6:55, then it was 6:56, :57, :58. I look down [at my phone] and he’s like, ‘What’s your code?’ ” Marshall said.

“Woody [Johnson, the Jets’ owner] completely shut him out.”

Fitzpatrick eventually made it to the Wednesday meeting. “I might have been three seconds late, which is a minute late, I guess,’’ he said. “But I wasn’t technically under contract, so I don’t think they can fine me.”
