Defensive tackle DeForest Buckner is listed as day-to-day after going down in practice Wednesday with a left ankle injury. Buckner was on the ground for several minutes before getting to his feet and walking gingerly on his own.
Chris Jones filled in at defensive tackle — also called the three technique — on base downs while rookie Solomon Thomas entered with the first-team unit on nickel downs.
Another would-be starter with an ankle injury, safety Eric Reid, is not listed on the team’s pre-practice report. He went through individual drills Wednesday but was held out of team sessions.
Four players — NaVorro Bowman, Joe Staley, Pierre Garcon and Jeremy Zuttah — are getting so-called “veteran days” today and will not practice.
