ST KILDA midfielder Jack Billings is set to miss four weeks after straining his right hamstring in Saturday’s NAB Challenge loss to the Brisbane Lions.

Billings sustained the injury in the opening minutes of the Saints’ first NAB Challenge hit out for the year.

The injury was to the same hamstring that kept Billings out of the final three games of 2014.

He is expected to be fit in time for round one.

Stay tuned to this afternoon for an exclusive interview with Billings.
