Brisbane Heat have suffered a significant pre-season setback after former captain Jess Jonassen was ruled out of the Women's Big Bash League (WBBL) 12 due to a hip complaint, the franchise confirmed on Monday. The Australian spinner is targeting a return to competitive cricket by New Year, with the Heat now in active talks to sign an international replacement before their season opener.

Second Straight Disrupted Season for Jonassen

This marks the second consecutive WBBL campaign that Jonassen has been unable to complete at full fitness. In the previous edition, she was sidelined for four matches after battling a shoulder injury that eventually became unmanageable. The recurrence of a different injury compounds concerns about her availability heading into what would have been a landmark season for the veteran spinner.

Jonassen said she was 'bitterly disappointed' to be absent from the start of the tournament, which gets underway on Thursday. In a club statement, she addressed the decision directly: 'Last year I was managing a shoulder injury and tried to play through until it got too much for me and was having an effect on both my own and the team's performances, as well as my mental health. We considered whether playing through injury was available again, but the advice was to have this period of recovery now, so I can be available for the rest of the season.'

Jonassen's Recovery Timeline and WNCL Target

The plan, according to Jonassen herself, is to resume training in December and be available for selection in the Women's National Cricket League (WNCL) thereafter. She added: 'The plan is to be back training in December and be ready to play again in our next WNCL fixture.' The Heat are hopeful she rejoins the WBBL squad later in the season once she clears fitness benchmarks.

Coach Sorell on the Challenge Ahead

Heat coach Mark Sorell acknowledged the blow candidly while emphasising that Jonassen would still contribute to the franchise from the sidelines. 'We're obviously pretty devastated for JJ,' Sorell said, adding: 'She has a good attitude to these sorts of things, and naturally we'll wrap our arms around her this week as we get ready to play. We'll lean into her experience around the group while she recovers and it will be a good chance for us to work with her around our match day planning.'

Replacement Hunt and WBBL 12 Opener

The Heat are currently in negotiations with an international player to fill the void left by Jonassen. The club confirmed the announcement is expected before their WBBL 12 tournament opener against the Sydney Sixers on Friday. The identity of the potential replacement has not yet been disclosed, though the urgency of the timeline narrows options to players not currently committed to other competitions.

Notably, Jonassen holds the distinction of being the most capped player in WBBL history, and is also the most prolific wicket-taker across men's and women's Big Bash competitions — underscoring just how significant her absence is for both the Heat and the broader tournament. Her injury-enforced absence will be closely watched as WBBL 12 takes shape in its opening weeks.
