GREEN BAY, Wis. (AP) -- After not seeing their preferred 11 defensive starters take a single preseason snap together, the Green Bay Packers are hoping a week of practice is all the unit needs to be ready for Sunday's regular-season opener at Philadelphia.

The Packers had the NFL's second-ranked defense last season. But second-year linebacker Clay Matthews missed all four exhibition games with a pulled left hamstring, and fellow linebacker Brad Jones missed the final three games with a shoulder injury.

Defensive end Cullen Jenkins missed the final two preseason games with a strained calf.

When the players returned to practice Monday after three days off, it marked the first time all 11 defensive starters worked together since the scrimmage.
