Stafford (back/hip) agreed to convert a $6 million roster bonus into a signing bonus, Field Yates of ESPN reports.
The agreement clears up $4.8 million in 2020 cap space for the Lions, allowing for a bit more room to maneuver. Stafford is closing out the year on injured reserve but should be healthy long before training camp. Most of Detroit's key contributors on offense are under contract for at least one more year, with slot receiver Danny Amendola and starting right guard Graham Glasgow the notable exceptions.
