Reports surfaced Wednesday that the Detroit Lions had reached an agreement with journeyman quarterback Matt Cassel.

NFL insiders Ian Rapoport and Mike Garafolo reported sources confirmed the signing.

The New England Patriots and Kansas City Chiefs mark some of the stops in Cassel's career on the way to Detroit.

Cassel notably started in 15 games for the Patriots during the 2008 season in which starting quarterback Tom Brady tore his MCL in the season opener.

The following season, Cassel left New England for four seasons in Kansas City.

As a starter, Cassel holds a 36-45 record.

The Detroit Lions starting quarterback gig decidedly belongs to Matthew Stafford who recently signed a $135 million deal.

Former Michigan quarterback Jake Rudock has been on the roster as a backup since the 2016 season when the Lions called him up from his practice squad position.

In 2017, the Lions experimented with a third quarterback during the preseason before signing sixth round draft pick Brad Kaaya to the practice squad.

The Indianapolis Colts signed Kaaya away from Detroit in December 2017.
