NASHVILLE — New York Jets defensive end Jermaine Johnson was stretchered off the field in the third quarter against the Tennessee Titans at Nissan Stadium on Sunday with a suspected serious injury to his right Achilles tendon.

If Johnson’s injury is long-term, it will put pressure on the Jets to resolve the contractual situation with Haason Reddick.

Johnson, who made the Pro Bowl last season as an injury replacement, went down while pass-rushing Will Levis with what appeared to be a non-contact injury. The cart came right off. Johnson’s teammates gathered around him as the former first-round pick buried his head in his hands. He put a towel over his head and then gave a thumbs-up as he was carted off the field.

Linebacker CJ Mosley left the field in the second quarter with a toe injury to his right foot. He was taken to the locker room and did not return.

The Jets had planned to pair Johnson and Reddick as their bookend pass rushers, but Reddick — acquired in a March 29 trade from the Philadelphia Eagles — has not reported because he is unhappy with his contract. If Johnson is out for the season, they would have to rely on Will McDonald and Michael Clemons as their top defensive ends. Both were projected as backups.

The Jets also played without cornerback DJ Reed (knee), who was cut at the last minute.
