FLORHAM PARK, N.J. (AP) — The New York Jets are uncertain if they'll have center Ryan Kalil against the New England Patriots on Monday night.

Kalil injured a shoulder during practice Thursday and is undergoing treatment. Coach Adam Gase initially said Kalil wouldn't practice Friday, but the 34-year-old veteran participated on a limited basis.

"Right now, (he's) more sore right now," Gase said before practice. "We're just going through the procedure that we have to go through with the training staff."

Jonotthan Harrison would start at center if Kalil can't play. Harrison was the projected starter until Kalil came out of retirement and signed with the Jets in August.

"We're lucky," Gase said. "Normally at that position, you don't have a guy that can jump in there and know it like he knows it."

New York could be without another starter on the offensive line as left tackle Kelvin Beachum didn't practice for the second straight day with an ankle injury. Brandon Shell, formerly the starter at right tackle, filled in after Beachum left the Jets' win against Dallas last Sunday and could do so again against New England.

The Jets had several other key players who didn't participate in team drills, leaving their status uncertain for the game, including: defensive end Henry Anderson (shoulder), tight end Chris Herndon (hamstring), running back/kick returner Trenton Cannon (foot/ankle), linebacker Neville Hewitt (neck/knee), guard Alex Lewis (neck), linebacker Albert McClellan (concussion) and safety Rontez Miles (not injury-related).

Linebacker C.J. Mosley was a limited participant in team drills, the latest step in his progress from a groin injury that has sidelined him since the season opener. Mosley declared Thursday he would play against New England unless he had a setback.

"I heard," a smiling Gase said of Mosley's announcement. "I love the fact that he's ready to go."

Cornerbacks Nate Hairston (knee) and Darryl Roberts (ankle) were also limited after not practicing Thursday. Nose tackle Steve McLendon (hamstring), right guard Brian Winters (shoulder/knee) and wide receiver Demaryius Thomas (hamstring) also were limited.

Rookie linebacker Blake Cashman was a full participant after being limited Thursday.
