The above link goes to the video-recorded moment just before the half-time siren of the 2006 elimination final (St Kilda versus Melbourne) where Fraser Gehrig marks on the lead, pivots, takes on the man on the mark, misjudges, gets tackled and rolls his ankle, whereupon Melbourne win and Grant Thomas quits.
More about the man on the mark, Nathan Carroll:
from Foxsports.com.au:
DISCARDED Melbourne defender Nathan Carroll has launched his last-ditch bid for a place on St Kilda's list for season 2009.
Carroll, dumped by the Demons after a series of alcohol-related off-field incidents, looked an angelic new face among the Saints players as they reported in for pre-season training on Monday.
