Jets quarterback Sam Darnold is officially doubtful for Sunday's game after not practicing for a third straight day because of a strained right foot. However, head coach Todd Bowles said there is still a chance Darnold will back up veteran Josh McCown.

"How he feels, how we think he compares to having Davis (Webb) as the backup," Bowles said of what will go into the decision. "We'll think about a lot of stuff."

Both center Spencer Long (knee/finger) and wide receiver Robby Anderson (ankle) did not take any team reps the past three days and are also listed as doubtful for Week 10. Anderson returned to the lineup against the Dolphins last Sunday after missing Week 8, but his ankle condition hasn't improved. If Long isn't able to suit up against the Bills, Bowles said he's very comfortable with Jonotthan Harrison starting at the pivot.

"His effort and energy," Bowles said regarding what he likes about Harrison, who relieved Long in the fourth quarter against the Dolphins. "We know he is very fast. He is athletic, he extremely smart and he does a good job. He can play multiple positions as well, so it won't be strange having him in there."

While the Jets could play Sunday without their starters at quarterback and center, Harrison is confident he and McCown can execute the team's game plan against the league's No. 3 defense.

"It's the same preparation by the offense," Harrison told Jets 360's Olivia Landis. "Josh is a true veteran. He's been doing this for a while, so he's able to jump in the fire and handle business whenever his number is called.

"We just have to compete and communicate. Make sure everyone is on the same page every play."

Earlier this week, cornerback Trumaine Johnson (quad) said he intends to play Sunday after missing five games and his name wasn't on the injury report. Defensive lineman Steve McLendon (ankle), WR Quincy Enunwa (ankle) and LG James Carpenter (shoulder) are also listed as questionable and were limited Friday.

Any Given Sunday
Even though the Bills hold league-lows in many offensive categories including points per game (6.2), point differential (-145) and giveaways (22), the Jets are not overlooking their AFC East rival.

"It's the NFL. Anybody can be beat in this league," safety Jamal Adams said. "You have to show up each and every Sunday. It doesn't matter the numbers that they're putting up or what they're not putting up. At the end of the day, they're a great football team, they're well coached and we're looking forward to the opportunity."

It's still unknown which quarterback will start for the Bills, but Matt Barkley, Nathan Peterman and rookie Josh Allen reportedly have taken equal reps with the starters this week. Barkley signed with the team last week and hasn't played yet for Buffalo, Peterman has appeared in four games (two starts) and thrown for 296 yards with one touchdown and seven interceptions, and Allen has missed the past three games with an elbow injury.

"Well, the thing for us is we've just got to go back and look at all the films," Jets defensive coordinator Kacy Rodgers said. "Usually in most breakdowns, you take the last four. So because they've had multiple guys play at the quarterback position we have to go back and study the whole season instead of the last four."
