The San Francisco 49ers have had an eventful day on Saturday and among the moves, they'll be losing one of the best players in their franchise's history. While San Francisco continues to focus on the 2020 NFL Draft, Joe Staley made his retirement official.

Staley walks away from the game after 13 remarkable seasons with the 49ers. Upon his decision to retire, San Francisco's front office released an official statement speaking about what Staley meant to the franchise.

“For the last 13 years, Joe Staley conducted himself in a manner that epitomizes the 49ers way and set a tremendous example for his teammates and our community,” said 49ers CEO Jed York, via the team's official website. “A consummate professional, one of the best players in the game and a great human being, Joe has left an indelible mark on this franchise and everyone he has come into contact with throughout his career. His passion, sense of humor and heart are just a few of the many traits that allowed him not only to be a team leader but also an ambassador for our game and the Bay Area.

Over his 13 seasons with the 49ers, Staley was one of the best left tackles in the NFL. While starting in 181 games in his career, the Central Michigan product made six Pro Bowls. Above all, he was part of two Super Bowl rosters with the 49ers.

Even though he never won a Super Bowl with the team, Staley was a phenomenal fixture on San Francisco's offensive line. With Staley retiring, the 49ers are replacing him with Trent Williams — who they traded for on Saturday. Despite Williams being a talented left tackle in his own right, he has some big shoes to fill next season.
