From Utah State, Mark Estelled signed as a free agent with Montreal in 2006. Estelle saw limited action in that first season, but took over as a regular on the corner in 2007. From 2008 to 2010, Estelle won East Al-Star honours at cornerback. Knee injuries limited Estelle to just 8 games in 2011 and breaking up his All-Star streak. Estelle returned to the Als in 2012, but his knee was not recovered enough and he was placed on the injury list for the season after just three days in trainining camp.
Estelle went to the Grey Cup three times with the Als, losing to Calgary in 2008, but picking up wins in 2009 and 2010 over Saskatchewan. Highlights of Estlle's six year career in Montreal were 11 interceptions and 3 fumble recoveries. In 2007, Estelle had a 78 yard pass interception return for his lone career CFL touchdown.
