— Redskins Coach Mike Shanahan confirmed that linebacker Brian Orakpo (shoulder) and safety Brandon Meriweather (knee) both are out for the rest of the preseason and that the goal is to get them ready for the Sept. 9 season opener.

— Shanahan praised Robert Griffin III’s effort in Saturday’s game against the Bears. He said that Griffin was close to making a play on the fumble late in the first quarter, which led to a Chicago touchdown two plays later. He said Griffin is learning the fine line between when to try to make a play and when to protect the ball even if taking a sack instead.

Shanahan said Griffin and Kirk Cousins both did well looking downfield and ignoring the rush.

Shanahan said he played Cousins an extended look to further evaluate him. Shanahan said he didn’t play Rex Grossman because “I know what Rex can do. . . . I didn’t want to have him go back to Chicago, where he started and took them to a Super Bowl and only play him one series.”

Shanahan said Griffin will likely play one series into the third quarter on Saturday.

— Running back Roy Helu (now both Achilles’ tendons are sore), safety DeJon Gomes (foot), cornerback Morgan Trent (knee, shoulder) and wide receiver Lance Lewis (groin) also sat out Monday’s practice.

— Linebacker London Fletcher practiced fully after missing Saturday’s game.

— Shanahan said running back Tim Hightower practiced but is a little sore. He will continue to prepare in hopes of playing Saturday, but is not definite.

— Guard Kory Lichtensteiger (knee) went through drills.

— Shanahan said young wide receivers Aldrick Robinson and Dezmon Briscoe “helped themselves” with their performances Saturday.

— Shanahan acknowledged that the defense was experimenting with some unusual looks from defensive backs against Chicago, and he said that overall he’s pleased with his secondary.
