Cricket West Indies (CWI) on Friday announced that they have brought in Shamarh Brooks as a concussion substitute from Nkrumah Bonner in the ongoing first Test against Australia at Perth Stadium.

Bonner had to leave the field on day three of the Test match after having copped a blow on the helmet off all-rounder Cameron Green's vicious bounce. He was batting at 16 off 47 balls and was involved in a 28-run stand for the second wicket with skipper Kraigg Brathwaite.
