The team parted ways Monday with placekicker Neil Rackers and cornerback Kevin Barnes, who was traded to the Detroit Lions, among others.

Shanahan said making roster cuts is the toughest part of his job.

Shanahan said Graham Gano “won the statistical battle” Neil Rackers “and that’s why he’s on our team.” The coach saw no need to drag out the kicking competition another game.

Shanahan said he will be talking to Jammal Brown when the tackle returns from New York, and will disclose a plan of action following his recovery.

Shanahan said that if there are no setbacks, running back Evan Royster should play on Wednesday against Tampa Bay, in the Redskins’ preseason finale. Shanahan said he still isn’t sure about Roy Helu’s status for the game.

Shanahan said fellow running back Tim Hightower had “some soreness” in his surgically repaired knee following Saturday’s game. “I’m a little concerned for him for this game,” Shanahan said of Wednesday’s preseason finale.

Tight end Chris Cooley attended practice as an observer because he “didn’t feel very well,” Shanahan said.

Shanahan said Tyler Polumbus “has done a very good job” and will start the season at right tackle.
