ESPN's Adam Schefter reports the New Orleans Saints have agreed to terms with restricted free agent guard Jahri Evans on a seven-year, $56.7 million dollar contract extension.

The $8.1 million dollar per year average would be the richest contract ever signed by an interior offensive lineman.

A fourth-round pick (108th overall) out of Division II Bloomsburg University in 2006, the 6-4, 318-pound Evans has started all 64 games at right guard for the Saints. Evans was named to his first Pro Bowl following the 2009 season, also earning first-team All-Pro honors.

Evans signed a three-year, $1.426 million dollar contract as a rookie, and played last season under a one-year restricted free agent tender worth $2.792 million dollars. Still not eligible for unrestricted free agency, Evans was tendered at the "First- and Third-Round" level this off-season, which before his long-term extension, would have paid Evans $3.168 million dollars in base salary in 2010.

Evans was the sixth-highest earner in the NFL's performance-based pay program, which ran from 2002-09. Evans banked an additional $782,363 from that program, which rewards players with high playing-time percentages and low base salaries.
