Blair reunites with former Niners defensive coordinator Robert Saleh in New York. Blair, a fifth-round pick in 2016, spent the 2020 season on the physically unable to perform list after suffering an ACL injury late in the 2019 season. Blair recorded 5.5 sacks and 36 total tackles in 2018. The 49ers reportedly re-signed Blair in April; it appears he did not pass the physical necessary to complete the signing. He'll be a rotational defensive lineman for Saleh's Jets.

That's pending a physical, which is never a given with the oft-injured lineman. Released in March, Blair has not played since November 2019 because of ACL/knee woes. If the 28-year-old can get back to full health, he will be a nice piece of rotational depth along the 49ers' front. 

Blair hasn't played a single down since suffering a torn ACL in November 2019, suffering a season-ending setback last year, too. He's totaled 1,184 snaps with the Niners since 2016.

Blair tore his ACL last November and was brought back on a one-year contract in March. He must have suffered a setback. The 27-year-old played 214 snaps before going down in 2019.
