The roster move means that rookie linebacker Reuben Foster is on course to take over the Mike linebacker position once he is completely healthy. On Friday, Foster was listed as questionable for Sunday's road game against the Washington Redskins. Even if he does play on Sunday, he is unlikely to see a heavy amount of playing time. Instead, Foster will likely only take the field in certain defensive packages.

"That's where we plan for him to play (when he returns)," Shanahan said. "I can't say this week. I still can't even say whether he's going to play or not this week. He hasn't taken a ton (or reps) there at Mike, we've always worked him a little but it has been Bo's spot and we do feel it's Reub's natural spot. Once he's fully going and back into the flow of things, which I can't promise you will be this Sunday, as soon as is, that will be his spot."
Foster is attempting to return from a high-ankle sprain that he suffered against the Carolina Panthers on September 10. He returned to practice this week but was limited.
