Career
In his National Lacrosse League career, Coyle played for the Detroit Turbos, the Ontario Raiders, the Toronto Rock, and the Colorado Mammoth. In 1994, Coyle played with the Detroit Turbos of the MILL, but was suspended indefinitely from the MILL for striking a referee. When the MILL became the NLL in 1998, it was decided that the suspension did not apply to the new league, and Coyle was signed by the Ontario Raiders.
However, just weeks before the 2005 season began, the league announced that the Ravens would not play in 2005, and Coyle immediately became a free agent.
During the 2008 season, Coyle announced that he would be retiring after the season.
