PHILADELPHIA (Reuters) - Michael Vick's return to the NFL elite received another boost when the Philadelphia quarterback agreed to a lucrative six-year deal on Monday that will make him one of the league's highest paid players.

The lucrative contract is worth $100 million, according to local media, and completes Vick's rehabilitation into professional football after he spent 18 months in prison following his 2007 conviction on dog-fighting charges.

The re-signing will be formally announced at a press conference on Tuesday.

"I'm very happy we were able to reach an agreement with Michael on this long-term contract," Eagles coach Andy Reid told the team's website (philadelphiaeagles.com). "It's a product of all the hard work Michael has done to better himself over the last couple of years, both on and off the field."

The 31-year-old Vick returned to the NFL in 2009 when he joined the Eagles as a backup quarterback.

An injury to former Philadelphia starter Kevin Kolb last season opened the door for Vick and the electrifying runner and passer threw for 3,018 yards and 21 touchdowns to go with nine rushing touch-downs as he reached his fourth career Pro Bowl.

His play-making ability is one of the prime reasons the Eagles are among the pre-season favorites to reach the Super Bowl.
