RICHMOND — The Redskins had a scare in practice Monday afternoon when first-round draft pick Brandon Scherff injured his right ankle midway through 11-on-11 drills.

The 6-5, 319-pound Scherff, who was recently switched from right tackle to right guard, had his ankle taped and watched the rest of practice from the sideline, while Spencer Long and Arie Kouandjio each got some time at his spot.

Tight end Niles Paul, elevated to starting status over incumbent Jordan Reed in advance of Thursday’s preseason opener at Cleveland, injured his left shoulder.

Both starters are being evaluated, a team spokesman said, so there was no immediate word on the severity of their injuries.

Linebacker Will Compton (groin) sat out practice while Keenan Robinson’s participation was cut short by team officials as a precautionary measure after a hard hit to his head.

A crowd of 4,133 was on hand for Monday’s return to practice of starting cornerbacks DeAngelo Hall and Chris Culliver, both of whom had been sidelined by groin injuries.

Wide receiver DeSean Jackson (AC joint) led the list of players still nursing injuries. He was joined on the sideline by tight end Logan Paulsen (toe); defensive backs David Amerson (sprained medial collateral ligament) and Jeron Johnson (hamstring); inebacker Trevardo Williams (hamstring); and receiver/return specialist Jamison Crowder (hamstring), who is expected to miss Tuesday’s practice, as well.
