The Miami Dolphins have signed Kiko Alonso to a four-year contract extension.

"It means everything," Alonso said. "This is where I want to be. I'm just excited that it's official that I'm staying here."

Alonso led the Dolphins with 115 tackles last season. Miami gave Alonso a first-round tender earlier this month to prevent the linebacker, a restricted free agent, from exploring his options with other teams.
