“He didn’t get surgery so I know he’s got a chance to” return, Shanahan said. “The good thing that has happened is Tyler Polumbus has done a good job.”

Brown has not practiced since he aggravated a hip injury on the day before training camp began. He remains on the camp version of the physically unable to perform list and no timetable has been given for his return.

The Redskins are without three starters on their offensive line. Left guard Kory Lichtensteiger is expected to miss the entire four-game preseason after undergoing arthroscopic knee surgery. Right guard Chris Chester suffered a sprained ankle this week and is likely to miss Thursday night’s preseason opener at Buffalo.

Shanahan played down the injuries, which he said he doesn’t believe will affect the Redskins’ offensive approach Thursday.

“It’s part of camp,” Shanahan said.

The Redskins made their assistant coaches available to media members before the team’s scheduled departure to Buffalo.

Shanahan said there were no discussions among the team’s coaches about giving quarterback Robert Griffin III more playing time during the preseason because he’s a rookie.

“There wasn’t any thought,” Shanahan said. “I wasn’t asked.”

Griffin is scheduled for a preseason workload that’s standard for a starting quarterback, beginning with approximately 12 to 20 plays Thursday.

Also, Shanahan said the starting nod being given Thursday to tailback Evan Royster is not necessarily an indication of which way the team is leaning in the competition for the starting running back job.

“Nothing is set,” Shanahan said.

Coach Mike Shanahan said Tuesday that Royster would start against the Bills and split carries with Roy Helu. Tim Hightower, who’s working his way back from a knee injury suffered last season, is not scheduled to play in Buffalo.

“Hopefully one of those guys will make our decision easy,” Kyle Shanahan said.
