Leroy Hill is back with the Seahawks.

Then again, he has never actually left, which is nothing short of shocking considering all that has happened the past four years. He has been injured, he has been arrested and he has entered the open market as an unrestricted free agent in three of the previous four offseasons and returned to the Seahawks every time.

The team announced Thursday it had agreed to terms to re-sign Hill and fellow linebacker Matt McCoy, each to one-year contracts. Hill did not return a message seeking comment on his return, and the team disclosed no further details.

Hill, 29, signed a long-term deal with the team in 2009, and had it renegotiated a year later after he was arrested on a domestic-violence charge in Issaquah. That charge was dismissed last year after he completed the terms of a stipulated order of continuance. Hill missed most of 2010 with an Achilles injury. He has been arrested, including twice in a span of 13 months that led to league suspensions for violating the NFL's personal-conduct policy and policy on substances abuse.

Hill put all that behind him last year and had one of his most productive seasons. He appeared in all 16 games for the first time in his seven NFL seasons and finished with 89 tackles, three off his season high. It was entirely drama free, too. At least it was until he was arrested in Georgia at the end of February, but even that disappeared, prosecutors dropping charges within days of the arrest.

Seattle drafted Hill in the third round in 2005, and cornerback Marcus Trufant is the only current Seahawk who has been with the team longer.

Seattle's plans at linebacker were one of the big unanswered questions this offseason. The team let middle linebacker David Hawthorne leave as a free agent (he signed with the New Orleans). The Seahawks signed veteran Barrett Ruud after Hawthorne didn't accept the team's last offer. K.J. Wright is established as the team's strongside linebacker, but bringing back Hill gives Seattle a proven player at weakside linebacker.

McCoy established himself as a special-teams standout for Seattle in 2010, and he had expanded into a role as a nickel linebacker last year before suffering a season-ending knee injury in the team's fourth game.
