The five-time Pro Bowl quarterback likely will miss the rest of the week's organized team activities. Kevin Kolb, a second-round pick last season, worked with the first-team offense in McNabb's absence.
McNabb hasn't played an injury-free season since leading the Eagles to the Super Bowl in 2004. He missed the final seven games in 2005 with a sports hernia, sat out the last eight games, including playoffs, in 2006 with a torn knee ligament and missed two games last year with a sprained ankle and injured thumb.
