Rookie Eddie Lacy's inevitable ascension to the Green Bay Packers' starting running-back job now appears to be fast-tracked. Coach Mike McCarthy said Monday that Harris is seeking a second opinion after the incumbent starter re-injured his knee in Friday's 17-10 preseason loss to the Seattle Seahawks. The need for a followup examination suggests the injury could be more serious than the tailback let on after the game. Lacy has been the Packers' clear-cut No. 2 back. Should Harris miss Week 1 versus the San Francisco 49ers, the No. 61 overall pick in the 2013 NFL Draft would be the favorite to handle starting chores. Source: NFL.com
