The New York Jets have brought on four additional players to their active roster ahead of their Week 4 matchup with the Denver Broncos, and Joe Flacco appears to be one of them (per Ian Rapoport of NFL Network).

They've also released backup quarterback Mike White, who served as Sam Darnold's reserve through Week 3. This was apparently the Jets' plan all along.

Flacco was always meant to more than likely serve as Darnold's backup. The former Broncos quarterback has been out since April with a neck injury that required surgery, making him inactive the first few weeks of the season.

How much production the Jets can rely on from Flacco against his former team in the Broncos on Thursday night should be put on a small scale. The 35-year-old quarterback hasn't seen action since last year while not being able to practice as well.

“The toughest part of it is really just feeling pretty good, but not being able to go out there and play and not being able to go out there and practice,” Flacco said on Tuesday during a virtual press conference, via SI.com. “The offseason was one thing, but once we got back here for training camp and everybody's doing their thing and throwing footballs and throwing individual drills and running seven on seven running team drills, that's where it kind of started to become tough just because I couldn't take part in that. When you're so close to the action, but not able to really do it, it can be frustrating.”

Flacco played just eight games for the Broncos during the 2019 season. He completed 65.3 percent of his passes while throwing for 1,822 yards along with six touchdowns.
