The Steelers waived Sternberger on Monday, Tom Pelissero of NFL Network reports.
Sternberger joined the Steelers' practice squad in November of last year and spent the rest of the season on the team's practice squad before he signed a futures deal in January. The 2019 third-round pick hasn't appeared in an NFL regular-season game since 2020, when he caught 12 of 15 targets for 114 yards and one score across 12 appearances with Green Bay.
