The team announced Tuesday the quarterback won't attend training camp and that he doesn't plan on playing football in 2015.
The younger brother of two-time NFL MVP Aaron Rodgers, the 26-year-old was signed to the Lions' practice roster in October and took part in B.C.'s minicamp last month.
Jordan Rodgers starred at Vanderbilt University for two seasons, but failed to stick with three separate NFL teams after college before trying his hand in the CFL.
The Lions also announced the signing of four international players on Tuesday — quarterback Grant Hedrick, kicker Anthony Fera, and offensive linemen Jason Foster and Josh Aladenoye.
The club's training camp opens Sunday in Kamloops, B.C.
