July 11 (Reuters) - ⁠Australia left-back Jordan Bos will ⁠miss the first three ‌months of the new season for Feyenoord after a knee injury at the ​World Cup, the ⁠Dutch club said ⁠on Saturday.

Feyenoord said Bos underwent successful ⁠surgery ‌on Saturday. His left knee was in ⁠a brace after he went off ​having ‌been clattered into during the ⁠first half ​of Australia's last-32 loss to Egypt on penalties in ⁠Dallas on July 3.

The 23-year-old ​started all Australia's matches at the World Cup, having overcome ⁠a run of serious hamstring injuries to earn a move to Feyenoord where he scored ​four goals in ⁠36 matches in his first season ​after moving from ‌Westerlo in Belgium.
