The 49ers list of injured players is long. It may be so long that they can’t suit up 46 players Sunday against the Cardinals.

14 players were either out of practice or limited Thursday, including tight end George Kittle and wide receiver Emmanuel Sanders. They were both out of practice for the second consecutive day.

The NFL season becomes a war of attrition through the final half of the year, and the 49ers are in a fierce battle now. Kittle hasn’t been officially ruled out, but Staley will miss a couple weeks, and DJ Jones is out at least for the Cardinals game. Robbie Gould hasn’t practiced since straining his quad early last week, and Matt Breida re-aggravated an ankle injury Monday night against Seattle.

Here’s Thursday’s practice report released by the team:
