While the injuries do not appear to be serious, defensive ends Arik Armstead and DeForest Buckner, the future bookends along the defensive line, were both injured during Sunday's practice within a 10-minute span, per Cam Inman of Bay Area News Group.


As Inman pointed out, Armstead hurt his left shoulder while Buckner injured his right arm. Armstead was a first-round draft selection in the 2015 draft while Buckner was selected in this year's draft. The two are friends and both played for Oregon.

Further confirming that neither injury seemed serious, neither Armstead nor Buckner received attention from the medical staff.
