Richard Sherman has agreed upon a three-year deal with the San Francisco 49ers worth as much as $39.15 million. The deal is heavy in incentives as Sherman returns from a torn Achilles.

"I'm thankful to John [Lynch, 49ers GM] and Kyle [Shanahan, 49ers coach] for believing in me," Sherman told Josina Anderson. "Some smaller details still getting ironed out, but #ShermInTheBay."

Sherman was released by the Seahawks on Friday.

Sherman played collegiately at Stanford.
