Green Bay -- The Green Bay Packers are about to award cornerback Charles Woodson for winning the 2009 NFL defensive player of the year award.

Woodson, who turns 34 in October, and the Packers have agreed on the terms of a contract extension that will bump up the 33-year-old corner's salary and increase the number of years on the deal. Woodson was scheduled to make $6.5 million in base salary over the next three seasons with the potential of an added $900,000 roster bonus each year.

The Packers probably felt compelled to boost Woodson's contract after Oakland cornerback Nnamdi Asomugha signed a six-year deal worth a reported $45 million, including $28. 5 million guaranteed and New York Jets cornerback Darrelle Revis signed a four-year, $46 million deal with $32 guaranteed.

The Packers have not announced the extension. Woodson was at practice Thursday afternoon and should be available during the open locker room session later this afternoon.

Terms of Woodson's extension aren't known yet. A source said the deal would probably be wrapped up in a day or so.

Update: ESPN's Adam Schefter reported it was a two-year extension.
