The Seahawks Wednesday reached an injury settlement with Robert Turbin, making the fourth-year running back out of Utah State a free agent. After he cleared waivers the past weekend following a sprained ankle in the third preseason game, the Seahawks placed Turbin on injured reserve, where he would have been lost for the season. The settlement allows him to pursue an NFL job after he’s declared healthy in five or six weeks.

Turbin’s injury allowed the Seahawks to sign RB Fred Jackson, released by Buffalo, to a one-year, $900,000 deal. The third running back for Sunday’s opener is rookie free agent Thomas Rawls.

Turbin could return to the Seahawks, but that’s not likely since NFL rules mandate that a player must wait six weeks after he is cleared to play to re-sign with the team that placed him on IR. That means Turbin is probably headed elsewhere and, unless Turbin signs a long-term deal with another club, he will become a free agent following the 2015 season.

The Seahawks selected Turbin in the fourth round of the 2012 draft. The 5-foot-10, 222-pounder rushed for 928 yards and caught 43 passes for 427 yards and three touchdowns in 48 career games.

Note

CB Justin Coleman, just signed to Seattle’s practice squad, left the club Wednesday when New England inked him to its 53-man roster.
