Green attended and played high school football at Benson Polytechnic High School in Portland, Oregon. He graduated in 2006. During his senior season, he rushed for 1,134 yards and 14 touchdowns to earn first-team All-PIL honors.
Green originally went to Butte College in Oroville, California, the same college that future Packers teammate Aaron Rodgers had played for in 2002. In 2008, Green lead the team to a 12–0 record and the junior college national championship. During that time he had 1,037 yards and 14 touchdowns rushing, he also scored two receiving touchdowns.
In his first year at Hawaii, Green played in all thirteen games as a running back. He had 453 yards and two touchdowns rushing, as well as 11 receptions for 98 yards and another touchdown. His best game at the season came against Utah State University, where he rushed for 110 yards on 10 carries. The Warriors finished the season 6–7.
Green was considered one of the better running back prospects coming into the 2011 NFL Draft. Scouts stated that Green was "thickly built and well-proportioned", with "competitive speed". However, he was also criticized for his ball-control, lack of power, and the fact that he played in "a pass-happy 'pistol' offense featuring wide splits against porous WAC defenses" and that he "was never asked to handle a heavy workload." He was projected to go as early as the third round.
Green Bay Packers
Green was selected by the Packers in the third round of the 2011 NFL Draft, with the 96th overall pick. During the 2011 preseason, Green appeared in three games for the Packers; he rushed for 23 yards in 16 attempts, and had one reception for 25 yards. Green made his regular season NFL debut in week 1 of the 2011 season against the New Orleans Saints. He received his first carries at running back during garbage time in week 4 against the Denver Broncos; he had three carries for a total of 11 yards. During week 7, Green injured his knee and missed the rest of the season, an injury that head coachMike McCarthy called "very unfortunate". During the 2012 season, Green had 135 rushing attempts for a total of 464 yards, and caught 18 passes for a total of 125 yards. He did not play in the Packers' final two regular season games or two postseason games, due to aftereffects of his 2011 knee injury. Green was released by the Packers on August 31, 2013.
Green was claimed off waivers by the New York Jets on September 1, 2013. During the 2013 season, he appeared in 13 games; he had 11 carries for a total of 35 yards, and 2 receptions for a total of 8 yards. In 2014, Green appeared in all four Jets preseason games, but was released on August 30, during final roster cuts.
Hamilton Tiger-Cats
In February 2017, Green signed with the Hamilton Tiger-Cats of the CFL. He played in the preseason, was released before the start of the regular season, then rejoined the team following the injury of running back C. J. Gable. Green played in his first CFL game on September 22; in a 24–23 victory over the BC Lions, Green had 13 carries for a total of 140 yards, and 2 receptions for a total of 15 yards. Green played five more games for the Ti-Cats in 2017, rushing for 447 yards and 5 touchdowns. Green earned the starting role for the 2018 season, however he suffered a hand injury just prior to the start of the season, requiring the Ti-Cats to convert defensive lineman Nikita Whitlock to a running back, and to sign John White. Green played very well when he was healthy, but missed 10 games with injury. In eight games he accumulated 604 rushing yards and 7 touchdowns. He also caught 17 passes for 205 yards with one touchdown. Jones and the Ti-Cats agreed to a contract extension on January 30, 2019. Despite being extended, and having great scoring production with 13 touchdowns in 14 regular season games played, Green was released prior to training camp.
