SCANS last night confirmed that Jack Watts partially dislocated his right ankle and broke his right fibula in Port Adelaide’s 16-point win over Carlton.

Watts suffered the injury after being tackled in the early stages of the final quarter.

Port Adelaide Head of Medical Services Tim O’Leary said Watts had surgery on his leg this morning.

“Jack underwent successful surgery earlier today and will commence his rehab process as soon as possible,” O’Leary said.

“Jack has obviously suffered a serious injury and will therefore be sidelined for an extended period of time. It’s too early to be putting a specific timeline on his recovery at this stage.”

Meanwhile, Port Adelaide midfielder Karl Amon suffered a medial sprain in his left knee during the first quarter of last night’s game.

Amon will undergo scans tomorrow to determine the extent of the injury.
