Royster is listed as day-to-day with a strained patella tendon in his right knee, and Helu is hobbled by turf toe, coach Mike Shanahan said Monday

 Royster had two carries for 21 yards and a catch for 12 yards Sunday. He hurt his knee with 7:02 left in the fourth quarter. Quarterback Robert Griffin III threw an incompletion at Royster’s feet, and Royster appeared to try to bend over to catch the ball before it hit the ground. But he was knocked over by defensive end Robert Geathers.

 Royster had to be helped off the field. After the game, he said he fell on his knee awkwardly. He walked with a limp on Monday. Royster said it’s the same knee that he tweaked midway through the preseason.

 Helu, meanwhile, had three catches for 20 yards, but didn’t appear to be injured at any particular point in the game.

 Shanahan said Royster aggravated a pre-existing turf toe injury on his right foot. Helu,  who missed two preseason games with bad Achilles’ tendons, wore a walking boot following Sunday’s game. He also is listed as day-to-day.

 Rookie Alfred Morris, who on Sunday rushed for 78 yards and a touchdown on 17 carries, is the only healthy running back on the roster.
