The Washington Redskins were awaiting word Wednesday on how long they will be without standout kick and punt returner Brandon Banks, who saw orthopedic surgeon James Andrews about his problematic left knee.

Coach Mike Shanahan Tuesday ruled the second-year pro out of Friday’s preseason game at Indianapolis. Banks was in Alabama Wednesday to see Andrews and is expected to seek a second opinion. It’s expected that he could miss a significant stretch of time as his surgically-repaired left knee continues to flare up after even a small amount of activity.

Banks had arthroscopic surgery on his left knee back in November, and returned to action two weeks later. He spent the offseason working to strengthen the knee, but has missed seven days of practice during training camp.

Banks on Friday recorded a 58-yard kickoff return against the Steelers, and returned a punt 19 yards. He wasn’t able to practice when the team returned to the field Sunday, and practiced in a limited capacity on Monday. But his knee began to swell after running only a few pass routes, and Banks missed Tuesday and Wednesday’s practices.

Shanahan didn’t yet know if Banks, who last season averaged 25.1 yards per kick return and 11.3 yards a punt return, would need surgery.

“We’ll wait and see what the doctor says, but it was a little swollen after running only a few routes, so that’s not a good sign,” Shanahan said.
