Wide receiver Michael Gallup has decided to retire rather than play this season for the Las Vegas Raiders, the club indicated Tuesday with the announcement he was placed on the reserve/retired list.

Gallup signed a one-year contract with the club in April.

The 28-year-old Gallup, who spent all six of his NFL seasons with the Dallas Cowboys, was placed on the list one day before the team's first training camp practice.

Gallup amassed 3,744 yards receiving and 21 touchdowns on 266 catches. His best season was in 2019, when he had 66 receptions for 1,107 yards and six scores.

The third-round selection in the 2018 draft out of Colorado State sustained a torn ACL on Jan. 2, 2022, while making a touchdown catch against the Arizona Cardinals. In his final two seasons with the Cowboys, he had his lowest yardage totals of his career: 424 in 2022 and 418 last season.

Dallas released Gallup in March. His one-year deal was worth up to $3 million with the Raiders, who saw him as the possible third receiver behind Davante Adams and Jakobi Meyers.

The Raiders also placed five players on the physically unable to perform list: linebacker Darien Butler, receiver Jalen Guyton, offensive tackle Kolton Miller and guards Jake Johanning and Jackson Powers-Johnson. Miller is still recovering from offseason shoulder surgery.
