Foster, who is recovering from a high-ankle sprain suffered during Week 1, was seen jogging and stretching with his teammates. However, once warmups were complete, Foster exited the practice field and walked to a side field for rehabilitation.
On Wednesday, head coach Kyle Shanahan said that he didn't believe there was any chance that Foster would play against the Cardinals.
Three players suffered concussions last Thursday night against the Los Angeles Rams. They are linebacker Brock Coyle, fullback Kyle Juszczyk, and safety Jaquiski Tartt. All three were limited during practice on Wednesday.
Below are the official Wednesday practice participation reports for both the 49ers and Cardinals.
