Mark Anthony Marshall (born 5 May 1987) is a Jamaican professional footballer who plays as a winger for Isthmian League Premier Division club Dulwich Hamlet.
He was a first-team regular for the club before he received a two-year ban from football after he was found to have the stimulant Methylhexanamine in his system following a routine drug test on Boxing Day 2011.
New manager Danny Wilson accepted an offer from Bournemouth to take the winger on a one-month loan in January 2009, but Marshall rejected the move.
He failed to establish himself in the first-team back at Swindon, despite the departure of Anthony McNamee, new loan signing Frank Nouble was preferred.
[20][21] Following the expiry of his ban, Marshall was signed by Coventry City on a short-term contract in February 2014 after impressing manager Steven Pressley on trial.
[22][23] He made his first competitive appearance in two years on 4 February, coming on as a 72nd-minute substitute for Carl Baker in a 2–1 win over Bristol City at Ashton Gate Stadium.
[24] In total he made 14 League One appearances during the 2013–14 season, but despite being popular with fans he was not offered a fresh contract in the summer by manager Steven Pressley.
[28] He scored seven goals in 49 appearances in the 2014–15 campaign, and it was reported in The Sentinel that his "combination of skill, pace and work rate made him a favourite among supporters".
[32] He made 38 appearances across the 2015–16 campaign, but started just eight league games, and was an unused substitute as Bradford were beaten by Millwall in the play-off semi-finals.
[36] Manager Stuart McCall praised Marshall's consistency and versatility, saying that "he crosses and shoots equally as well with both feet" and "is one of the highest for assists in the league".
[39] On 17 June 2017, Marshall signed a two-year contract with League One club Charlton Athletic; "Addicks" manager Karl Robinson said he was "one of our main targets" alongside former Bradford teammate Billy Clarke.
[47] The season was curtailed early due to the COVID-19 pandemic in England and Northampton went on to qualify for the play-offs; Marshall played as a 31st-minute substitute for Nicky Adams in the behind closed doors Wembley final as the "Cobblers" recorded a 4–0 victory over Exeter City to secure promotion into League One.
[50] He barely featured towards the end of Curle's reign as he chose to play without wingers before Marshall returned to the first-team after Jon Brady took charge in February.
[51] He scored two goals in 33 games in the 2020–21 season and was not offered a new contract when the club's retained list was published in May following Town's relegation out of League One.
[66] Former teammate Tom Pope stated that Marshall has "terrific self-belief" and will continue to try to beat his marker even if he is struggling to find success in the match.
