Seattle Seahawks cornerback Richard Sherman signed a four-year, $57.4 million contract on Wednesday that makes him the NFL's highest-paid cover man.

Sherman said the deal includes $40 million in guaranteed money.

"The goal has always been to stay in Seattle and continue to play for the Seahawks," Sherman wrote on his blog. "With this chapter closed, I can continue to focus on what is important -- defending our Super Bowl Championship and being the best cornerback in the NFL.

"This is a great moment for my family, foundations and the people who supported me to this point. Hard work and execution got me to this moment, the Seattle Seahawks have backed up that respect with this contract. The terms of my deal are 4 years for a total of $57.4M with $40M guaranteed. There is no other city or team that I would want to play football for."

Sherman, 26, has emerged as one of the NFL's top defensive players since being selected by Seattle in the fifth round of the 2011 draft.

The 6-foot-3 Sherman led the league with eight interceptions last season when the Seahawks won their first Super Bowl championship in franchise history.

Sherman's deal comes two weeks after the Seahawks wrapped up a four-year, $40 million contract with Earl Thomas that made him the highest-paid safety in the league.
