It looks like the contract that Brandon Marshall signed with the New York Giants back in March is going to be the final one of his career. 

The veteran receiver revealed on Saturday that he plans to retire after his two-year, $12 million deal with the Giants expires following the 2018 season. 

"Two more years, get my Super Bowl, have a little bit more fun, and then I'm going to go change the world in the mental health space," Marshall said, via ESPN.com. 

Marshall was at a health and fitness expo that was being held at MetLife Stadium when he made the announcement. The 33-year-old receiver was at the expo to talk about how his life has changed since being diagnosed with borderline personality disorder in 2011. 

The disorder is a mental illness characterized by a persistent instability in "moods, behavior, self-image, and overall functioning," according to the National Institute of Mental Health. The disorder and also have negative impact on one's emotions, relationships and behaviors.

Marshall regularly does work for Project 375. The purpose of the group, which was co-founded by Marshall, is to eradicate the stigma surrounding mental health by raising awareness and improving care for those in need.

Before he retires, Marshall will be aiming to get to the postseason for the first time in his 11-season career, and the Giants might be the perfect team to help him make that happen. After going 11-5 last year, the Giants' offense should only get better now that Marshall's on the team.  

Since being drafted by the Broncos in 2006, the former fourth-round pick has gone over 1,000 receiving yards in nine of his 11 seasons. Marshall is also only two years removed from a 2015 season with the Jets where he led the NFL with 14 touchdown catches. 

With a receiving corps that also includes Odell Beckham and Sterling Shepard, the Giants might just have the type of offense that can help Marshall "get" that Super Bowl win that's he's been coveting since he entered the league.
