49ers' Alex Mack ends NFL career after 13 seasons

San Francisco 49ers center Alex Mack is retiring after 13 seasons in the NFL, he announced Friday.

Mack, who previously played for the Cleveland Browns and Atlanta Falcons, made the seventh Pro Bowl of his career last season.

The 36-year-old boasts three second-team All-Pro nods (2013, 2016, 2017) and was a member of the NFL 2010s All-Decade team.

Mack was drafted by the Browns in the first round of the 2009 draft and spent seven seasons in Cleveland before joining Atlanta as a free agent in 2016. He signed with the 49ers last offseason.

The center played in 196 regular-season games and was known for his consistency and durability. The veteran suited up for every regular-season game in all but two of his 13 campaigns.

San Francisco will gain over $4 million in cap space, as Mack agreed to rework his deal, according to Field Yates of ESPN.

Jake Brendel is first in line to replace Mack with the 49ers.
