Australian sprinter O'Callaghan suffers injury ahead of worlds

SYDNEY : Australian Mollie O'Callaghan, who owns the fastest times of the year in both the 100 and 200 metres freestyle, has injured her knee a few weeks out from the start of the world championships in Japan.

The swimming at the World Aquatics Championships in Fukuoka begins on July 23.

O'Callaghan underlined her quality at this month's Australian trials when she upset Olympic champion Ariarne Titmus to win the 200 in one minute 53.83 seconds, then edged Tokyo gold medallist Emma McKeon to win the 100 in 52.48 seconds.

Taylor said O'Callaghan, who already owns two Olympic and two World Championship relay gold medals at the age of 19, was an integral part of the Australia team.

"She's a very versatile athlete across the freestyle and backstroke events which is extremely beneficial to us across the relays," he said.

"We're fortunate to have a number of our athletes, female athletes in particular, that are like
