The New York Jets' already disappointing season took a more ominous turn when rookie quarterback Zach Wilson suffered a knee injury in the second quarter of a 54-13 loss to the New England Patriots on Sunday.
Wilson said he felt a "pop'' and a "twist'' in his knee when Patriots linebacker Matt Judon fell on the back of his legs early in the second quarter. The second overall draft pick eventually walked off the field after spending several minutes being examined on the turf.
Wilson said the initial diagnosis was an injury to his posterior cruciate ligament, and he was to have an MRI on Monday.
"Initially you feel good. But you never know,'' Jets coach Robert Saleh said.
Also for the Jets, linebacker Jamien Sherwood was evaluated for a concussion, came back into the game, then left with a calf injury. Another linebacker, Quincy Williams, did not return after he was checked for a possible concussion.
Veteran Patriots safety Devin McCourty left with an abdominal injury. The Patriots also lost defensive lineman Carl Davis (wrist), tight end Jonnu Smith (shoulder), linebacker Harvey Langi (knee) and right guard Shaq Mason (abdomen).
Chiefs quarterback Patrick Mahomes was evaluated for a concussion late in Kansas City's 27-3 loss to Tennessee. He took a knee to his head on a sack by Denico Autry but said after the game he was fine.
