RENTON, Wash. -- All-Pro cornerback Richard Sherman has signed a four-year contract extension with the Seattle Seahawks.

Sherman announced the news on his website Wednesday ahead of a news conference called by the team. Sherman wrote that the extension is for $57.4 million with $40 million guaranteed. Sherman wrote there is no other team or city that he would want to play for.

Sherman's deal wraps up a solid off-season for the Seahawks prior to the NFL draft. Seattle re-signed defensive end Michael Bennett, reached extensions with coach Pete Carroll and All-Pro free safety Earl Thomas and has now locked up Sherman for the long term.

Sherman is a two-time All-Pro selection. He had eight interceptions each of the past two seasons.
