Despite lingering concerns about his knee, Teddy Bridgewater was able to land a one-year deal with the New York Jets this offseason. However, that doesn’t necessarily mean Bridgewater is guaranteed to be part of the team’s roster once the season begins.

According to NFL Network’s Mike Garafolo, Bridgewater’s not a lock to make the Jets roster until he can prove he’s completely healthy.

Bridgewater has played just a handful of snaps in the last two years as he suffered a serious knee injury in practice in 2016. While he successfully made his return to play late in the 2017 season for the Minnesota Vikings, it remains to be seen if he is still the same promising young quarterback who led the Vikings to the playoffs in 2015.

It’s that promise which the Jets bet on when they signed him to his one-year deal. But Bridgewater would only have a $500,000 cap hit, which means the Jets likely won’t hesitate parting ways with him if he doesn’t prove to be all the way back.

The Jets currently have four quarterbacks on their roster with Bridgewater, Josh McCown, Christian Hackenberg, and Bryce Petty. They’ll most likely add one more if they draft a quarterback with the No. 3 pick as expected, and part ways with at least one of Hackenberg and Petty.

The Jets obviously believe in Bridgewater’s ability enough to bring him in and likely want to see him play a role in this team. But his knee is a big enough question mark that it could potentially be a deal-breaker for him in New York.
