Sunday's 26-18 loss to the Dolphins was enough for the Jets to handle, but New York nearly left Miami with two key injuries.
First, defensive tackle Steve McLendon made his exit after he suffered an apparent shoulder injury.
Then there was safety Jamal Adams, who underwent an evaluation for a possible head injury.
After the game, the updates from first-year head coach Adam Gase on the defensive leaders was mixed.
"McLendon, he didn't finish with a neck (injury)," Gase said. "We'll evaluate that tomorrow."
Gase had better news on Adams, though, who appears to have emerged an initial concern in good health.
"Jamal, we got evaluated for him -- he got pulled out of the game -- evaluated for a concussion," Gase said. "He's not in the protocol. That's everything, so he should be OK going forward."
Both of the Jets were already battling through injuries before the Jets (1-7) trekked down to the Dolphins (1-7) in Week 9.
McLendon managed to work back from a hamstring issue in time, while Adams fought through a foot ailment.
After the Jets' third straight loss, they hope to have their two defensive stalwarts back for Week 10 next Sunday against the Giants (2-6).
"At the end of the day, we didn't play well enough to win," Gase said. "Too many penalties. Too many plays where we're in position for, we're not making the plays. So we need to. We weren't good enough on third down, on both sides of the ball. Just didn't do enough."
