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.
