MAGGIE MacLachlan and Liz McGrath are preparing to spend time on the sidelines due to injury.

MacLachlan dislocated her shoulder in Round 1 against West Coast and again in a later training session.

The forward will undergo surgery on Friday to correct recurrent shoulder instability, so will not be eligible for selection for the remainder of Season Seven.

McGrath returned to full training this week following a hamstring strain, but unfortunately suffered a lateral ankle sprain during a ruck contest at training on Tuesday night.

She is expected to miss three to four weeks.

Injury list
Maggie MacLachlan, shoulder (season)
Liz McGrath, ankle (3-4 weeks)
Gemma Houghton, ankle (approx. 1 week)
