Stafford signed a deal Tuesday with the Steelers, Jim Wyatt of TitantsOnline.com reports.
Stafford is coming off his most productive season of his NFL career in 2016 with the Titans, as he recorded 52 tackles, one sack and an interception. The safety will now join Pittsburgh for its offseason workouts leading up to training camp, and Stafford should have a fair chance at securing a depth role on Pittsburgh's final roster this season.
