The Jets have replaced starting quarterback Ryan Fitzpatrick with Geno Smith, who will make his first start of the season Sunday against the Ravens.
Despite having four quarterbacks on the active roster, head coach Todd Bowles said only Smith was considered to replace Fitzpatrick, citing a lack of practice time from Bryce Petty and the inexperience of rookie Christian Hackenberg as his reasoning.
Petty, 25, was selected in the fourth round of the 2015 NFL Draft out of Baylor.
"Bryce (Petty) has only practiced for a week and Hack's (Christian Hackenberg) not ready. It was Geno or Fitz," said Bowles. "He needs to practice a good bit. He needs to practice a good bit and get some reps. A week coming back after over a month, he needs to practice a little while."
The second-year QB yet to appear in a regular season NFL game.
Hackenberg, 21, was selected in the second round (51st overall) in the 2016 NFL Draft out of Penn State. Bowles is hesistant to use his rookie QB, who he views as fourth on the depth chart, until he further develops.
"You've got to get reps to get ready. He's a rookie quarterback and he's got three in front of him," said Bowles of Hackenberg. "He's not going to get enough reps to be ready to throw in there like that. He's getting plenty of scout team reps. He's learning poise in the pocket and is getting experience that way."
After replacing Fitzpatrick on Monday night in the Jets' 28-3 loss to the Cardinals in the fourth quarter, Smith completed four of six passing attempts for 31 yards and threw an interception.
For at least Sunday, Smith will serve as the team's starting QB and Fitzpatrick will assume the role of backup.
