It's a done deal pending a physical, NBC 10's John Clark has learned.
The former Cincinnati Bengal is expected to replace long-time Eagle "Big Jon" Runyan at right tackle.
Andrews, 29, is the older brother of current Eagles offensive guard Shawn "Big Kid" Andrews. The brothers could wind up playing next to each other on the Eagles' right side next year.
Andrews is a power blocker who makes the Eagles younger on the right side than they were with Runyan.
The departure of Runyan may shock some Eagles fans. "Big Jon" is well known as a pitchman and community figure in the Tri-State area.
From a football perspective the Eagles had to be worried about Runyan's age and that he is coming off microfracture knee surgery.
Andrews is also coming off off-season surgery on his knee. Doctors repaired the anterior cruciate and medial collateral ligaments in his right knee after he was hurt in the 15th game of last season.
Andrews is expected to be ready for the start of the 2009 campaign, according to ESPN.
The details of the multi-year deal remain unclear but Andrews is expected to make around $7 million per season, a source told the Mike Florio at the "Sporting News" blog.
Andrews is currently in Philly and the deal should be made official at a Saturday morning press conference.
