The Steelers have signed tight end Alize Mack to their practice squad while starter Vance McDonald’s availability for Monday night is unknown.
McDonald was seen in a sling on Tuesday at UPMC Rooney Sports Complex after leaving Sunday’s game with a shoulder injury.
The Steelers relied on back-up Xavier Grimble in that game and also have fifth-round rookie Zach Gentry on the roster and second-year player Christian Scotland-Williamson on the practice squad. Running back Jaylen Samuels has also played tight end in some positions.
Mack was a seventh-round pick out of Notre Dame by the New Orleans Saints in this spring’s draft, but was released by New Orleans last week. Mack also worked out for the Browns this week.
He missed a good amount of his training camp this summer with an injury and did not play in any preseason games. The Saints waived him in final roster cuts and added him to the practice squad. He was waived from their practice squad on Sept. 20.
To make room on the practice squad for Mack, the Steelers released inside linebacker Robert Spillane.
