Seahawks release Aldon Smith

The Seattle Seahawks released defensive end Aldon Smith, the team announced Wednesday.

The team released him because he violated its trust in connection to an off-field matter and the decision isn't football-related, a source told ESPN's Brady Henderson.

Smith signed a one-year deal with Seattle this offseason.

The 31-year-old was arrested on a second-degree battery charge in April. The alleged incident took place two days after Smith signed with the Seahawks.

The former All-Pro has been arrested on multiple drunk-driving charges and he's missed four seasons because of suspensions.

Smith was reinstated by the NFL last spring and signed a one-year deal with the Dallas Cowboys. He tallied 48 tackles, five tackles for loss, and two fumble recoveries.

A first-round selection of the San Francisco 49ers in 2011, Smith racked up 44 sacks in his first four campaigns before off-field issues took him away from the game.
