Mystics star defender Catherine Hall has been ruled out of the rest of the ANZ Premiership season due to injury, leaving her Silver Ferns Commonwealth Games prospects in serious doubt.

Hall could be seen on crutches when the Mystics beat the Stars 57-51 on Saturday to sit third on the ANZ Premiership ladder after six rounds.

Hall had to leave the court late in round five when it looked like she jarred her foot.

The Mystics on the weekend said they were waiting on scan results to determine the seriousness of the injury but the franchise issued an update on Thursday.

Mystics head coach Tia Winikerei said Hall underwent surgery to her foot on Monday.
