The Raiders added certain safety depth on Saturday afternoon, promoting fully healthy rookie Tevin McDonald from the practice squad.

Veteran safety Taylor Mays was released in a corresponding move. He was questionable on the team’s injury report after missing most of the practice week with an ankle injury.

The Raiders made a switch at that spot, seemingly due to Mays’ availability. He hadn’t played much defense after starting in Week 2 for the injured Nate Allen, relegated to special teams work since the second half of that game.

McDonald was active once this season. He was promoted from the practice squad for that Week 2 win over the Baltimore Ravens, but he did not play.

The Raiders need healthy bodies in the secondary and safety especially, even though TJ Carrie was upgraded from out to questionable on the team’s injury report.

Mays was signed near the end of the preseason, cut just before the end of the preseason and signed again after Allen tore an MCL in his knee in the season opener.
