No, you're not reading that incorrectly.
GWS' injury woes have worsened, to the point where they've copped four injuries in their game against Carlton.
Greene, Deledio, Taylor and Simpson have all picked up injuries during the course of the game.
This has seen them forced to use two players less, instead choosing to have them on the bench to rotate players.
It hasn't stopped them though, as they're set to win by 100+ against the Blues.
