Costigan has been fighting since 2009 our of Ireland won her two amateur matches and now has a professional record of 5-0. Her pro debut was in 2010 and looks like she took some time off until 2013 and won 4 in a row since August 2014 with her last win against Noellie Molina with the Cage Warriors promotion won that match by armbar and only needed two minutes of the first round.

She enters an Atomweight division stacked with some great talent and top fighters in Herica Tiburcio and Michelle Waterson and is probably looking for a challenge in 2015 to become a contender for title sometime soon. Hopefully she will make the Vegas card where Cyborg is headlining in July.
