I recall the media were throwing around talk of a "12 month recovery" for a torn achilles. It's a terrible injury and not one that you would want to shortcut the recovery process.
So I'd guess she will be sitting out this coming WNBA season for sure. She'll probably ease herself back into the game just training for quite some time, so it'd suit that purpose for her to stay in Australia (maybe at the AIS, maybe with a WNBL team next summer?) without the pressure of expectation she'd have in America or China to get better ASAP and suit up.
