The Dolphins and Howard agreed to a five-year contract, according to his agent.
The new deal gives Howard the most guaranteed cash in the history of the game.
Howard had three years and $39 million left on the five-year, $75 million contract he signed in 2020, but he was unhappy with the deal entering the 2021 season. The 2016 second-round pick requested a trade in July, saying he didn't feel appreciated by the organization that drafted him.
Howard was the second-highest paid defensive back on his own team when Miami signed Jones to a five-year, $82.5 million contract.
After Howard requested a trade, the Dolphins restructured his contract to make it easier for him to stay and promised to negotiate a new contract after the 2020 season.
The Dolphins general manager said at the annual meeting last week that Xavien has done a lot of good things for the organization. When we drafted him, I was here. He was my second pick. I am looking forward to him helping us win.
Howard forced two turnovers and one of which he returned for a touchdown. Howard has more picks than any other player since he entered the league.
