Redskins running back Clinton Portis expects his injured groin to keep him out of this weekend's game against the Packers. Portis told 106.7 The Fan that he's awaiting the results of an MRI on his left groin, which he injured against Philadelphia this past Sunday. "I don't think the team would even let me attempt to go and try to play on Sunday," Portis said. "But who knows? ... I'm going to take my time and make sure I'm healed."
