Thanks to Ron L for pointing this out (from packers.com):
DEFENSE: CB CHARLES WOODSON, GREEN BAY PACKERS
Woodson tied for the NFC lead with three interceptions and had an NFL-best two interception-return touchdowns during September. All three of his interceptions came in the fourth quarter and each one resulted in a Packers’ touchdown. Against Detroit in Week 2, Woodson sealed the victory with a pair of fourth-quarter interceptions, including one he returned 41 yards for a score. In Week 4, the 11-year veteran had a 62-yard interception-return touchdown against Tampa Bay to give the Packers a fourth-quarter lead.
In his 11th year from Michigan, this is Woodson’s first career Player of the Month Award. He is the second consecutive Packer to be honored on defense (ATARI BIGBY, December 2007) and the first cornerback in franchise history to win the award. Bigby and Woodson are the only Packers defensive backs to be honored.
