The Lions have clearly been in the market for offensive line over the past few months.
Bradfield, 28, originally signed on with the Jaguars as an undrafted free agent out of Grand Valley State. He spent the first three years of his career in Jacksonville before signing on with the Falcosn at the start of the 2014 season.
The Cardinals wound up signing him to a future/reserve contract in January, but he was unfortunately among their final roster cuts.
Bradfield appeared in two games last year while playing for the Falcons.
Sherrod, 26, is a former first-round pick of the Packers back in 2011. However, his NFL career was derailed by a very serious compound leg fracture.
Sherrod wound up being active for eight games while playing for the Chiefs last year.
