The dual-code athlete signed with the reigning Premiers on a half-season contract which will see the 24-year-old train and play with Roar for the rest of the calendar year.

McCormick has made over 60 appearances with Adelaide United and Canberra United defender but also created history when the Adelaide Crows won the inaugural AFLW Premiership in 2017.

She will return to Adelaide at Christmas to commence pre-season training for the Crows and is set to be available for round one.

W-League and AFLW seasons have generally overlapped for the previous years with players either choosing to see out W-League and missing round one or training and playing both competitions.

“It was really hard for me to think about deciding between the sports this year,” McCormick told Crows media.

“I didn’t want to give up either, but I knew that it was coming to a point where I would have to, given the overlap.

“Playing a full season of soccer and missing out on footy at the start of the season, I didn’t really want to do it again, I wanted to play a full season and give it more of a crack.

“That’s why the half-season works out really well for me, I still get to have my foot in both and enjoy playing both,” she said.

McCormick joins Katrina Gorry, Abbey Lloyd, Summer O'Brien, Natalie Tathem, Allira Toby and Kaitlyn Torpey who all re-signed for the club on Tuesday.
