By doing so, the Seahawks won't have Carpenter under contract through the 2015 season.
Drafted 25th overall four years ago, Carpenter would have been assigned a $7 million salary for the 2015 season if they had opted to do so.
Carpenter was a 10-game starter in 2013 as the Seahawks won the Super Bowl.
Carpenter has started 26 of 32 career games played in three NFL seasons.
He's under contract through next season.
