The Miami Dolphins are signing defensive lineman Zach Sieler to a three-year contract extension worth up to $38.65 million that includes $20 million guaranteed, a source told ESPN's Adam Schefter on Sunday.
Sieler, 27, has appeared in 53 straight games for the Dolphins since joining the team as a waiver claim in December 2019. He has totaled 10 sacks and three forced fumbles for the Dolphins.
Prior to Sunday's new deal, Sieler was set to become a free agent after the 2023 season.
The extension also comes as fellow defensive lineman Christian Wilkins has been seeking a new contract before entering the 2023 regular season on the fifth year of his rookie deal.
