The 49ers on Tuesday announced a pair of roster moves. Running back Marlon Mack was released after a brief stint on the active roster, and veteran defensive lineman T.Y. McGill was added to the practice squad.
Mack joined the 49ers after RB Elijah Mitchell was injured in Week 1. He was initially on the practice squad before being elevated to the active roster. He was inactive Sunday in Carolina and played in five special teams snaps in the two games he did play. NFL Media’s Tom Pelissero reported the 49ers expect to re-sign Mack to their practice squad
