The search for a suitable backup quarterback continues for the Jets.

In the wake of Geno Smith's fractured jaw and the team's decision to promote No. 2 quarterback Ryan Fitzpatrick, the Jets brought in veteran Matt Flynn for a physical Friday.

According to a source, he did not have a workout. The issue could be his balky hamstring, which resulted in his release from the Patriots on Monday.

Flynn, 30, has thrown 17 touchdown passes and 11 interceptions in seven NFL seasons. He played the majority of that time with the Packers but also spent time with the Seahawks, Raiders and Bills before he signed on to be the Patriots' third-string quarterback on June 11.

The Jets don't appear to be in a rush to sign another quarterback, but that hasn't stopped them from looking. Rex Grossman and Tyler Thigpen also have been cited as potential backup options, but no moves have been made.

Instead, the Jets took the field in Detroit Thursday night with their current stable of quarterbacks -- Fitzpatrick, 2015 fourth-round draft pick Bryce Petty and Jake Heaps.

After the Jets' 23-3 loss to the Lions, Petty stressed that his struggles on the field were just a byproduct of the NFL learning curve.

"I have a lot to learn," said the former Baylor star, adding that he didn't realize he would be replacing Fitzpatrick as early as the second series of the game. "It's just a different game coming from what I was in as far as system-wise. I've made a lot of strides since the beginning of camp. I feel good about where I'm at. Not that I've mastered anything, but I'm getting good chances. There are certain plays for whatever reason I'm comfortable with and there's certain plays that kind of have my head scratching a little bit."

Petty, who was 10-for-18 for 50 yards, said the more reps he gets now, the better he'll be in the future. "It's huge for me because every rep is a learning experience, whether it's good or bad," he said. "So it's about getting in there and it's a process . . . Just taking it for what it is and learning as much as I can."

Fitzpatrick looked steady in his Jets debut, but that's mainly because he mostly was asked to hand off to running back Chris Ivory on his only drive of the night. The first-team offense did go 10 plays on its initial drive, but a third-and-1 drop by tight end Jeff Cumberland forced the unit to settle for a field goal.

"I wish I would have thrown a little bit better pass on the last one, completed it and we would have stayed on the field and got seven points," Fitzpatrick said. "But I thought it was nice to get out there and establish the line of scrimmage and be physical up front like we did.

"I felt comfortable. It was nice -- just the procedure of it, and to get in and out of the huddle, to run some silent count, to get the plays and the motions and everything communicated and not having any pre-snap penalties. In that regard, I thought we did a good job."
