Veteran DE Chris Clemons will retire after 12 NFL seasons

Veteran defensive end Chris Clemons has informed the Seattle Seahawks that he's retiring.

Clemons, 34, signed a one-year deal with the Seahawks earlier this offseason. The contract details suggested he was going to have to compete for a roster spot.

Clemons had three sacks in 16 games (seven starts) last season with the Jacksonville Jaguars. During his previous stint with the Seahawks (2010 to 2013), Clemons piled up 38 sacks in 62 games.

The 12-year veteran began his career in Washington before joining the Oakland Raiders and then the Philadelphia Eagles. After four seasons with the Seahawks, he spent two years in Jacksonville.

Mike Garafolo of NFL Network was first to report the news.
