The Jets earned their first win of the season on Sunday, but lost a key member of their defense in the process.

Edge rusher Jermaine Johnson suffered a non-contact injury that had all the hallmarks of an Achilles injury, and head coach Robert Saleh confirmed after the 24-17 win over the Titans that that was the injury. Johnson will undergo an MRI to confirm that diagnosis.

Johnson also spoke to reporters after the game and said he felt like someone stepped on the back of his leg. Johnson was coming off a season of 8.5 sacks, but it appears he won’t be adding to that total this season.

Will McDonald had a pair of sacks on Sunday, but the Jets will need help from the pass rush now that Johnson is out of the picture. They have Haason Reddick under contract, but he has been holding out in hopes of a new deal. We’ll see if Johnson’s injury changes the Jets’ stance on not giving him one.
