After a few cameo appearances on loan Marcus joined the Poppies on a permanent basis in January 2010. Marcus scored his first goal for the club away at Barrow as the Poppies ran out 2-0 winners. 2010-11 was a special season for Marcus as under new boss Marcus Law, he developed as an attacking full back, not only impressing his gaffer, but also he won the Supporters Player of the season and Vice –Presidents Player of the season. Carrying on from where he left off Marcus was the Poppies best player from the start of the 2011-12 season, but with crippling finances, he became the victim of the annual pre-Christmas clear out, joining rivals Mansfield Town.
