SANTA CLARA — Punter Thomas Morstead is joining the 49ers’ offseason overhaul on special teams via a pipeline from the New York Jets.

Morstead, on his social-media accounts this morning, foreshadowed Tuesday’s signing by posting a photo of himself outside Levi’s Stadium and writing: “Grateful is an understatement! #49ers”

His signing to a one-year deal came in conjunction with the 49ers announcing the release of Mitch Wishnowsky, their punter the previous six years who went on Injured Reserve last season with a back issue.

After special teams miscues throughout last season, the 49ers have made sweeping changes this offseason, from hiring Brant Boyer as special teams coordinator and adding kicker Greg Joseph to compete with Jake Moody. Boyer, Joseph and Morstead all were on last year’s Jets team that opened the season coached by Robert Saleh, who got fired after four games and is now reprising his 2017-20 role as the 49ers’ defensive coordinator.

That Jets’ connection also was found in another move Tuesday as the 49ers changed out linebackers, waiving DaShaun White and signing Chazz Surratt, who played his past three seasons with the Jets and had 10 special teams tackles last year.

Two weeks ago, the Jets released Morstead, a 16-year veteran who was on his second stint with the franchise. He began his NFL career in 2009 as a fifth-round draft pick out of SMU, and he became the New Orleans Saints’ all-time leading punter through 12 seasons, the first of which included a Super Bowl win.

Morstead split 2021 with the Jets and the Atlanta Falcons, then punted for the Miami Dolphins in 2022 before joining the Jets in 2023, when he led the NFL with 99 punts for 4,831 yards.

Morstead had a 40.7-yard net average last season, down from his career average of 41.5 yards.

Wishnowsky ranks first among all 49ers punters with an all-time net average of 40.7 yards per punt. He had a career-low 36.3-yard net average last season through nine games, before going on Injured Reserve in November and being replaced by Pat O’Donnell.

Wishnowsky, 33, missed time in training camp with knee irritation. He is fifth in franchise history with 310 punts and 14,142 yards.

Morstead and Joseph were teammates for only the final couple of weeks last season. The 49ers announced Joseph’s signing last week, providing veteran competition for Moody, who struggled last year in his second season and has since altered his mechanics to a two-step approach on kicks, according to The Athletic.

Another major change came earlier in the offseason when the 49ers replaced long snapper Taybor Pepper with Jon Weeks, who, at 39, is as old as Morstead.

Ethan Waugh is returning to the 49ers as a personnel executive. He worked in the 49ers’ personnel department from 2004-21 before spending the past three years as the Jacksonville Jaguars’ assistant general manager
