Dunn Done for 3-4 weeks

(AP) - As if they didn't have enough troubles, the Atlanta Falcons revealed today that running back Warrick Dunn will miss three to four weeks after having back surgery.

Dunn, who rushed for a team-high 1140 yards last year, hurt his back during offseason workouts and underwent the surgery on Saturday.

The team held off revealing the news while it dealt with the federal indictment of quarterback Michael Vick on charges related to dogfighting.

If the 32-year-old Dunn needs a full month to recover, he would miss all of training camp and the first two preseason games. But he should be back in time for the September 9th opener at Minnesota.

Jerious Norwood, who rushed for 633 yards in a promising rookie season, will move up to the first team while Dunn is out.
