GREATER Western Sydney has been dealt a huge blow with Josh Kelly to be sidelined with another calf injury.

Kelly reported soreness after the Giants' loss to Adelaide and scans revealed a calf strain, which will sideline him for up to five weeks.

The 29-year-old was sidelined for four weeks earlier in the year with a calf strain, with this setback on the opposite calf.

The Giants have lost six of their past eight matches and have fallen to 10th on the ladder ahead of hosting Carlton on Saturday night.

GWS could regain Nick Haynes from a hamstring injury this week, while Harry Rowston will be sidelined indefinitely with a back issue.
