The Lions signed former Redblacks defensive back Winston Rose Monday.
He was released by Ottawa last week.
Rose played in four games with the Redblacks last season making 21 tackles. He spent time in 2016 on the Argos practice roster. The 24-year-old went unselected in the 2016 NFL draft and signed as a free agent contract with the Rams and saw action in the preseason that year with the Colts.
