The Redskins were without starting left guard Kory Lichtensteiger and backup inside linebacker Jonathan Goff. Lichtensteiger received Saturday off to rest his surgically repaired knee, but wasn’t said to have suffered any setbacks. But, he wasn’t at walk-through Monday morning, either. Goff injured his surgically-repaired knee on Saturday, and was scheduled to have an MRI.

Without Lichtensteiger, Washington went with Maurice Hurt in the starting lineup.

The interior of the Redskins’ line has had some struggles early in camp, and they continued Monday as the members of Washington’s defensive front broke free frequently and harassed Robert Griffin III. The quarterback would spin away from the tags of would-be tacklers and make a play downfield. Had the defensive players been permitted to hit the quarterback, the outcomes of those plays likely would have been different.

Backup tackle Willie Smith injured his left knee during 1-on-1 drills. Linebacker Rob Jackson overwhelmed Smith with a bullrush, and Smith fell backwards and grabbed his knee. After being tended to by trainers, Smith walked around, but only watched the rest of practice.

Fullback Darrel Young and receiver Josh Morgan both suffered early injuries and watched practice with each of their left quads wrapped.

Activated from the PUP list today, free safety Tanard Jackson went through some rigorous side work, running, jumping and catching passes from strength coach Ray Wright. Jackson must go through one more conditioning day, and is expected to practice Wednesday.

Anthony Armstrong turned a busted play into a highlight. Kirk Cousins attempted a pass to backup tight end Logan Paulsen, but safety Reed Doughty deflected it into the air. Armstrong was running in the same area and made a juggling catch and took off for a touchdown.

London Fletcher said the biggest area of improvement in Perry Riley’s game is his pass formation recognition. Riley has looked good in pass coverage, as he did today when he ran with Leonard Hankerson and knocked a pass away from the wideout.

Griffin showed off his speed during 11-on-11 work in the red zone. The quarterback dropped back, but could find no open receivers. Flushed from the pocket, Griffin took off to his left and won a foot race with Josh Wilson to the end zone.

Rookie defensive back Richard Crawford picked off a deflected Cousins pass in the end zone for the seventh-round pick’s second INT of camp.

Cousins threw interceptions to Reed Doughty and London Fletcher as well.

The play of the day belonged to Griffin, but not for passing or rushing skills. After driving his team downfield, Griffin lined up at the 10-yard line, and completed a pass to Chris Cooley, who turned and got to the 1, but fumbled. Linebacker Bryan Kehl scooped up the ball and went the distance of the field ... almost. Griffin ran Kehl down and shoved him out of bounds around the 5-yard line to save a touchdown.
