The Saints signed Callaway to a contract Thursday.
The move comes after the Saints waived tight end Tommy Hudson (undisclosed) with an injury designation. Callaway spent the first four years of his career in New Orleans, starting in 2020. His best season came in 2021, when he posted 46 catches for 698 yards and six touchdowns across 17 regular-season games. Callaway signed with the Steelers in January after appearing in just three games in 2023, but he was let go by Pittsburgh on Tuesday. With Equanimeous St. Brown dealing with a hamstring injury, Callaway has the opportunity to earn a spot as a depth wide receiver behind Chris Olave, Rashid Shaheed and Cedrick Wilson.
