San Francisco 49ers DE Arik Armstead (hamstring) is week-to week with a hamstring injury, according to Matt Barrows of The Athletic.

Footballguys View: The 49ers have quite the assemblage of first round talents on the defensive line with Armstead, Solomon Thomas and DeForest Buckner, but it doesn’t look like the team will get to tinker to find the most potent combinations for a bit in camp.
