Justin Green (born April 30, 1982) is an American former professional football fullback.
Green attended the University of San Diego High School and was a student and earned three varsity letters in football and two in basketball.
That record has since been broken in 2005 by Demetrius Sumler, who also attended the University of San Diego High School.
He shredded his knee with just four weeks left during the 2006 season, however, had earned his way back into the starting lineup during the preseason in 2007.
After spending the 2008 season out of football, Green was signed to a future contract by the Arizona Cardinals on January 13, 2009.
In February 2012, Green was hired as the running backs coach for the Montana Grizzlies, his alma mater.
