According to a freelance NFL reporter Michael Silver report, San Francisco 49ers center Alex Mack will retire after a 13-year NFL career. Mack’s retirement has been the source of speculation all offseason long, and it seemed even more likely this morning when the team restructured his contract to create more than $4 million in salary-cap space.
The Cleveland Browns drafted Mack with the 21st overall pick in the first round of the 2009 NFL Draft. He immediately slotted into Cleveland’s starting lineup and emerged as one of the best centers in the league, a conversation he would belong to until his retirement.
