49ers' Arik Armstead: Not practicing

Armstead (foot) was a DNP in San Francisco's practice Wednesday, Eric Branch of the San Francisco Chronicle reports.

It's not surprising Armstead missed Wednesday's practice as he's been dealing with this foot injury since Week 3. The 6-foot-7 defensive tackle will have two days of practice before missing Sunday's game against the Rams, which would be his fourth consecutive game out.
