Medhurst joined Collingwood in 2007 in the deal which saw Chris Tarrant become a Docker, and Ben Reid, draft selection eight, join the Magpies. Despite playing his 100th match (his first in Magpie colours, round one against the Kangaroos), Medhurst began the season slowly, injuring his foot during a four-goal performance against Richmond in round three, which sidelined him for much of the season. Medhurst returned to face Fremantle in round 10 at the MCG, and Collingwood won by 10 points. Neither Medhurst nor Tarrant were among the goals, sharing three behinds between them.
