49ers sign veteran punter Thomas Morstead, replacing long-time punter Mitch Wishnowsky.

The San Francisco 49ers signed veteran punter Thomas Morstead, cutting incumbent punter Mitch Wishnowsky after six seasons. Morstead, a former Pro Bowl player, averaged 40.7 net yards per punt last season with the New York Jets. The move aims to improve the team's special teams unit, which struggled last year. The 49ers also signed linebacker Chazz Surratt and released DaShaun White.
