Monroe is also a former Jacksonville Jaguar, and reportedly drew interest from the New York Giants this off-season. Instead, he wants to move on and focus on the next phase of his life.
The big man signed a five-year, $37.5 million contract with the Ravens in 2014, with $17.5 million in guaranteed money. In two seasons since signing that deal, Monroe started only 17 games. He has missed time with injuries to his knee, ankle and shoulder, as well as dealing with a concussion.
Those health issues made the need to retire young that much more obvious to him. Monroe wants to focus on his health to make life with his family that much simpler. Monroe stated after the announcement "this was not an easy decision to make, but I know it's the right one for me, my health and my family."
