Marshall would spend the next three and a half seasons in Miami, starting as a forward and eventually drifting to the midfield and then defense. After the Fusion folded following the 2001 season, Marshall was selected by Los Angeles Galaxy as the ninth pick of the 2002 MLS Allocation Draft and helped LA to victory in MLS Cup 2002.
On 13 June 2007, Marshall received a red card for a tackle which broke the leg of FC Dallas forward Kenny Cooper in the 89th minute. The red card carries a mandatory one-game suspension and $250 fine, but the MLS Disciplinary Committee decided unanimously to extend the suspension two additional games and an additional fine of $1,250.[2]
Toronto FC
Marshall was traded to Toronto FC for Edson Buddle on 13 June 2007 after five seasons with the Galaxy.[3] Marshall cemented his place in Toronto's defense, and went on to make 16 starts during the 2007 season. Marshall managed to get revenge on his former side when Toronto earned their first win of the 2008 season in Los Angeles.
Seattle Sounders FC
Marshall was traded to Seattle Sounders FC on 10 February 2009 for allocation money.[4] He scored his first goal for the Sounders against Chicago Fire as the game finished 1–1. He also assisted a goal by Steve Zakuani in a match against San Jose. However, in the 86th minute in a match against D.C. United, Marshall accidentally scored an own goal with his head, and the game finished 3–3. He scored his second goal for the club on 17 October, in a game against Kansas City Wizards.
Return to the Colorado Rapids
After the 2010 MLS season Seattle declined Marshall's contract option and Marshall elected to participate in the 2010 MLS Re-Entry Draft. On 15 December 2010 Marshall was selected by Colorado Rapids in Stage 2 of the Re-Entry draft.[5] Marshall agreed to the terms of his contract on 3 January 2011 officially completing the transfer.[6]
Marshall was released by Colorado on 16 November 2012.[7] He entered the 2012 MLS Re-Entry Draft and became a free agent after going undrafted in both rounds of the draft.
International
Marshall was a regular with the Jamaica national team. He appeared in 83 matches from 2000 to 2010 before retiring from international football in January 2010, after appearing versus Canada.
He joined FC Cincinnati in February 2021 to coach their under-19 academy team and future under-23 squad. On September 27, 2021, Marshall was named interim head coach of FC Cincinnati's senior team for the remainder of the 2021 season following the dismissal of Jaap Stam.[11] On February 22, 2022, FC Cincinnati announced that Marshall will be the first head coach of the team's MLS Next Pro reserve team, FC Cincinnati 2.[12]
