It’s been a few days since Rand Getlin of NFL Media first reported that Seattle was signing Butler to a contract.
Last week, the Seahawks brought in Butler and CB Chimdi Chekwa for workouts, so he was clearly on their radar.
Butler, 28, is a former fifth-round pick of the Steelers back in 2010. Since then, Butler has played for a number of teams including the Cardinals, Redskins, Bills, Chargers, Buccaneers and most recent for the Lions.
Detroit elected to sign Butler to a future/reserve deal back in January, but he was unfortunately among their final roster cuts at the start of the season.
In 2014, Butler appeared in 11 games and recorded 14 tackles and a pass defense.
