The San Francisco 49ers have signed six-time Pro Bowler Alex Mack on a three-year deal via free agency.

Mack joins the 49ers after five NFL seasons with the Atlanta Falcons, having originally been drafted by the Cleveland Browns in the first round in 2009.

The 35-year-old spent his first seven seasons in Cleveland before signing a five-year, $57.5million contract in Atlanta before the 2015-16 campaign.

"The 49ers, obviously there's a connection with Kyle Shanahan, and him as a head coach and the offense he runs, that always has been something that I know it's a system I can be really good in," Mack said on Thursday.

"It's an offense I know I can excel at, so it was a very good fit between a good team and a good spot with a good coaching staff and a place I can be a good player in."

"We are excited to add another Pro Bowl player to our offensive line," 49ers general ,anager John Lynch said.

"Throughout his career, Alex has been a model of consistency. His leadership and high character will be felt throughout our team and community."

Mack, who grew up in California, has had a decorated career, as a three-time Second-Team All Pro (2013, 2016 and 2017) and being named in the NFL's 2010s All-Decade Team.

He made 90 consecutive regular-season starts until a concussion in the 2020 season ended that run.

The 49ers missed the NFL playoffs in 2020, finishing with a 6-10 record under head coach Kyle Shanahan, who remains in charge.

San Francisco have already added cornerbacks Mark Fields and Briean Boddy-Calhoun and tight end Daniel Helm this off-season.
