"With Quinnen, it was an injury that he sustained last week just doing drills here at the facility," Jets general manager Joe Douglas said on ESPN's Bart & Hahn. "We're still in the process of just making sure the imaging's right and setting everything up, but we feel good about him being back and ready to go full strength at training camp."
Williams likely will have surgery to repair the injury, sources said.
This means he will miss OTAs and minicamp. Based on the timetable, he should be ready in mid-July. The expectation is that he will be ready for the start of training camp, Douglas said.
Drafted third overall in 2019, Williams emerged last season as the Jets' top defensive player. He recorded a team-high seven sacks and added two forced fumbles in 13 games.
Williams missed six games in his first two seasons, including the final two games of the 2020 season due to a concussion and neck injury.
The new coaching staff expects Williams to flourish in the new 4-3 front, which should allow him to play more aggressively than the previous 3-4 scheme.
"I absolutely love Quinnen," coach Robert Saleh said recently. "Really excited to get the seat belt off of his harness and let him go. In this scheme, to get him going vertical, to get all that mass moving in the direction that he needs to go, I'm really excited about the potential that he's going to have."
News of Williams' injury was first reported by NFL Network.
