Report: Lions sign Matt Cassel to back up Matthew Stafford

Tennessee Titans QB Matt Cassel will undergo thumb surgery.

The Detroit Lions have brought in veteran quarterback Matt Cassel to back up starter Matthew Stafford, per NFL Network’s Mike Garafolo.

Cassel hasn’t been a starting-caliber quarterback in years. However, he is a capable backup who has a connection with Lions general manager Bob Quinn and head coach Matt Patricia, both of whom are former New England Patriots, the same as Cassel.

The past two years with the Tennessee Titans, Cassell has made an appearance in six games, starting two when Marcus Mariota went down with injuries.

Over the course of his 13-year career, he’s started 81 games, earning a record of 36-45 with the Patriots, Kansas City Chiefs, Minnesota Vikings, Buffalo Bills, Dallas Cowboys and Titans. He’s a career 58.9 percent passer who has passed for 17,449 yards with 104 touchdowns and 81 interceptions.
