The move comes after Dolphins' starting center Mike Pouncey asked for a release earlier that day. The two teams swapped 2018 seventh-round picks in the deal.
Pouncey was approached about taking a paycut this year and instead it was reported that he wanted an extension to which the Dolphins declined. After signing a three-year deal, Kerley was released before the season opener after San Francisco made a handful of signings in free agency.
A three-time Pro Bowl player, Pouncey was selected 15th overall by Miami in the 2011 NFL Draft.
For Pouncey it is an end to his career in Miami and he informed local media that he left everything on the field for the Dolphins, had no regrets, and would forever be a Miami Dolphin. Four-time Pro Bowl guard Josh Sitton agreed to terms with Miami on a two-year deal that could be worth almost $18 million including incentives, said his agent, Jack Reale. While he is 28 years old, his previous injuries are a concern.
"I gave this city everything I had", Pouncey told Schad. With his release, the Dolphins save $7 million on their salary cap. "We'll see what the next chapter is", he told the Post. "When Kyle (Shanahan) and I arrived last offseason, we knew right away that he was a well-respected leader in the locker room and a true professional".
Over the course of his seven years in San Francisco, Kilgore played in a total of 74 regular season games (39 starts) and six post season games.
Kilgore won the 49ers' Bobb McKittrick Award for the first time last season, awarded annually to the offensive lineman who best exemplifies the dedication, excellence and commitment of their former offensive line coach.
Sitton entered the league with the Green Bay Packers in 2008 and spent five seasons with the club.
