The veteran running back broke the news on Twitter.
His statement read:
After 9 years in this whirlwind business they call the NFL, I am proud to announce that I am hanging up my cleats. I've had an amazing run and I appreciate all of the support from the fans through the good and the bad. The New York Giants are a great organization and I am proud to have been a part of it for so long. I love my coaches and my teammates and will miss them as well as the game itself but I am healing well from my surgery and I look forward to running around with my kids for years to come!
As you'd expect, plenty of sportswriters praised the former New York Giant. While he was never one of the best players in the league, Jacobs remained a fan favorite and commanded the respect of those around him.
Jacobs spent eight of his nine years with the New York Giants. During that time, he ran for 5,087 yards and 60 touchdowns on 1,136 carries. He was a workhorse in the backfield who cut his teeth with his inside runs.
New York fans will likely remember Jacobs fondly for the role he played in both of the Giants' Super Bowl wins. He led the team in rushing in 2007 en route to the first win and played a great foil to Ahmad Bradshaw on the 2011 team.
This news doesn't come as a major surprise. Running backs in the NFL as a whole have a short shelf life, and few are able to make it past nine or 10 years. All of those carries begin to add up after a while, especially for guys like Jacobs who are more physical runners.
The nine-year veteran also had to deal with injuries throughout his career.
Although Jacobs' on-field performance had been waning in recent years, he had a locker-room presence that will be difficult to replace next season.
