San Francisco 49ers second-year DL DeForest Buckner is unlikely to practice with the team this week after aggravating a low-ankle sprain during Friday's 27-17 preseason win over the Kansas City Chiefs. While the 49ers don't seem too concerned about the injury, he was listed as "out" on Monday's practice participation report.

DL Ronald Blair (groin) and WR Aaron Burbridge (hamstring), who was one of the team captains on Friday, also will not practice on Monday.

Due to the injuries, the 49ers will reportedly bring in two defensive ends for a workout – Leger Douzable and Ricardo Matthews.

S Jimmie Ward, who has missed all of the 49ers' training camp practices with a hamstring injury, remains on the team's physically-unable-to-perform list.

Below is the 49ers' Monday player participation report leading into practice at 10:15 a.m.
