One, soreness was lingering in Kerney's surgically repaired shoulder, making it unclear when he would be able to return. Two, the Seahawks are not going to challenge for the Super Bowl this season. Three, the team liked Brandon Miller enough to the undrafted rookie free agent for depth after the Falcons released Miller this week.
The Seahawks need Kerney to get healthy for next season. He has produced for them when healthy, but injuries have required surgeries during recent offseasons.
Kerney's salary jumps to $4 million next season. He also has a $3 million roster bonus. The deal runs through 2012 with base salaries in excess of $5 million per season beginning in 2010.
