Winstead and the Steelers agreed on a contract Sunday, Alan Saunders of SteelersNow.com reports.
Winstead is coming off of a strong spring season with the Louisville Kings of the UFL, reeling in 29 of 46 targets for 474 yards and three touchdowns. The wide receiver spent the majority of the 2023 campaign with the 49ers' practice squad, but he has yet to make his NFL debut, and he'll look to compete for a spot on Pittsburgh's practice squad ahead of the 2026 season.
