RENTON, Wash. --
The Seahawks and free agent offensive lineman Breno Giacomini have agreed to a two-year contract extension after Giacomini proved to be a valuable backup on Seattle's offensive line.
The Seahawks confirmed the deal on Friday. According to the NFL Players Association website, Giacomini will make $1.5 million in base salary for the 2012 season and $3 million in 2013.
News of Giacomini's deal comes as a league source tells ESPN NFL Insider Adam Schefter that Seahawks director of pro personnel Will Lewis is leaving after 13 years with the team.
Giacomini played in 15 games and made eight starts on the Seahawks offensive line last season, filling in at a variety of spots after Seattle lost starters Russell Okung, James Carpenter and John Moffitt to injuries. Giacomini made $600,000 in base salary last season.
Giacomini is the first of Seattle's 18 unrestricted free agents to re-sign with the club.
Lewis has interviewed for other front office positions in the past and is expected to draw interest now.
