PHOENIX -- The Seahawks liked what they saw from Keary Colbert in practice in the days after they acquired him from the Broncos in September. There wasn't much to like from him during games, however, and that's apparently why Seattle released him Tuesday.
Colbert dropped what should have been a routine completion for a first down on a critical third-and-12 play against the Dolphins in Week 10. The Seahawks expect Deion Branch to return this week. Releasing Colbert appears to be a direct response to his struggles. Seattle remains relatively thin at the position. The depth doesn't improve without Colbert.
