Hawthorne signed a one-year, $1.38 million extension that will keep him in Seattle through the 2011 season. Hawthorne, an exclusive rights free agent during the 2010 offseason, signed a one-year tender that paid him $645,000 this season.
According to the NFL players association database, Hawthorne will make $900,000 in base salary for the 2011 season. It's a raise of more than $200,000 from what he is making this season.
He also received a $350,000 signing bonus.
Hawthorne replaced the injured Leroy Hill at outside linebacker this season and has now started 22 games over the past two seasons.
Hawthorne's first break came last year when he took over the starting spot from middle linebacker Lofa Tatupu when he was lost for the season with a pectoral injury.
Signed as an undrafted free agent out of TCU before the 2008 season, Hawthorne leads Seattle with 66 tackles and one interception for the NFC West-leading Seahawks (5-6).
