Miller (oblique) signed a reserve/future contract with the Seahawks on Monday, Curtis Crabtree of Sports Radio 950 KJR Seattle reports.
Miller was set to return from injured reserve when he was waived by the Falcons on Dec. 22. The 23-year-old will now try to make Seattle's roster in 2021. The Seahawks could use depth at cornerback, but Miller may need to impress on special teams to secure a roster spot.
