Who will start against Bills, Josh McCown or Sam Darnold?

FLORHAM PARK, N.J.  -- Sam Darnold took the shotgun snap and tossed a perfect pass to Jermaine Kearse in the left side of the end zone Friday.

That was at an indoor practice, though. Can the Jets now count on their rookie quarterback tossing passes outdoors Sunday in Buffalo?

After missing the last three games with a strained right foot, Darnold practiced fully for the third straight day. Unlike the previous week, there was no “questionable” designation on the injury report.  But Josh McCown also practiced fully Friday after two limited days because of a back issue, and he also had no designation under “game status” on the report.

While the arrows seem to point toward Darnold being out there again, coach Todd Bowles wouldn’t commit to that.

“I will decide that on Sunday,” he said. “Sam and Josh have both had good weeks.”

Bowles  also can keep the  Bills guessing this way.  So what will be the big factor in the decision?

“Talking it over with the coaches and making it,” Bowles said. “ . . .  Just have to decide whether [Darnold’s] ready or not.”

Running back Isaiah Crowell, who is questionable with a toe injury but said he will play, gave Darnold a positive review after this latest practice. “I felt like he looked good,” Crowell said. “He always looks good.”

Darnold needs more game experience, though. Despite not having  played since Nov. 4, he still leads the NFL with 14 interceptions. Four came in his last game at Miami.

“He’s got to get better with reads -- and he will with playing time -- progressions and getting in and out of the huddle, which he’s been doing a good job at before he got hurt,” Bowles said.

The Jets are out of the playoff puzzle for the eighth straight year, standing at 3-9 and riding a six-game losing streak. That includes a humbling 41-10 loss to  the Bills (4-8)  with McCown starting on Nov. 11 at MetLife Stadium.

The offense didn’t find the end zone much in Darnold’s last three games and the last three with McCown. The unit produced five touchdowns in the six games, including none in the 26-22 loss at Tennessee last Sunday. The Jets, who ran 33 times for 156 yards, had five field goals and a pick-6.

“I feel like we did good committing more to the run,” Crowell said. “We were right there. … I just feel like we’ve got to just learn how to finish and keep fighting hard. I know we’ve got what it takes.”

Notes & quotes: Wide receiver Robby Anderson (ankle), tight end Jordan Leggett (knee) and defensive back Buster Skrine (shoulder/hip) are questionable . . .  Here’s defensive lineman Leonard Williams on Jets fans who want them to keep losing at this point: “At the end of the day, the fans may want to lose and get a [higher] draft pick, but  at the end of the day, the players just don’t. We’re going to be the ones playing and we’re going to be the ones that want to win.”
