Jets veterans David Harris and Nick Mangold had MRIs on Monday and there was “nothing negative,” according to coach Todd Bowles.

Harris, the Jets’ middle linebacker, has a sore hamstring and Mangold, their seven-time Pro Bowl center, has a sore knee. The injuries forced both to exit early from Sunday’s 31-13 loss in Pittsburgh.

The Jets (1-4) don’t play again until next Monday night in Arizona, but on a conference call Monday, Bowles said it’s “too early to tell” if Mangold and Harris will be available to face the Cardinals.

“Nick is a huge part of what we do on offense,” quarterback Ryan Fitzpatrick said on a separate call. “He handles the communication. I thought Wesley [Johnson, Mangold’s backup] stepped in and did a nice job. We’ll see where that stands this week.”

In other injury news, Darrelle Revis is “progressing,” but Bowles isn’t sure if he’ll practice tomorrow. The cornerback has been nursing a mild strain in his left hamstring since last week and did not play Sunday.

With Revis out, cornerback Darryl Roberts impressed in his NFL debut with two tackles and two passes defensed against the Steelers, but he left the game after injuring a shoulder. He’s scheduled for an MRI.

Bowles said safety Calvin Pryor dealt with an injury during the game, and that’s why Rontez Miles played more defensive snaps.

Right guard Brian Winters wasn’t healthy enough to play against the Steelers either, but he’s almost out of the concussion protocol, Bowles said.
