They support injured forearms (6)

I believe the answer is:

slings

(Other definitions for slings that I've seen before include "Arm bandages; drinks" , "Supporters" , "Looped bandages for limb support or missile throwers" , "'''... to suffer the ... and arrows of outrageous fortune'' (Hamlet) (6)'" , "Catapults or arm supports" .)

I've seen this clue in The Irish Times.
