Karen Rolton, the Australia Women's captain, will undergo an MRI scan on her twisted left knee tomorrow. Rolton, 31, injured herself while fielding in Australia's last-wicket win over New Zealand in Brisbane.
The injury occurred in the 18th over of New Zealand's innings as Rolton turned to walk back to her fielding position.
"I'm not exactly sure how it happened, but I felt a twinge in my left knee as I was walking back to my fielding mark," Rolton told reporters. "I moved myself to another fielding position to see if it would settle down before coming off the field. I will have some scans on the knee tomorrow and get some further advice from a specialist."
Kirsten Pike, Australia's 12th player, replaced Rolton on the field. Rolton returned to bat at No. 9, however, and scored a valuable unbeaten 16 to take Australia to a penultimate-ball win.
