Greater Western Sydney forward Brent Daniels' day has been cut short after suffering a hamstring injury against Adelaide.

The Giants goalsneak was subbed out of the match at Adelaide Oval in the opening quarter, with medical sub Matt Buntine coming into play.

Daniels managed just the three disposals and one behind in the first quarter, with the Giants leading the Crows by seven points at the first break.

The injury is the latest in a string of setbacks for GWS, with captain Stephen Coniglio (ankle), defensive duo Phil Davis (calf) and Nick Haynes (hamstring), ruckman Braydon Preuss (shoulder) and midfielder Matt de Boer (hamstring) all sidelined for an extended period.
