Bravo was hit by a bouncer from Jasprit Bumrah late on the third day of the Kingston Test, leading to his stem guards falling off his helmet. However, he did face two deliveries to end the day unbeaten, but left the field early on day four, having passed a concussion test on the conclusion of the third day's play.

West Indies captain Jason Holder later claimed that the heat may have played a part in Bravo feeling dizzy to be eventually taken off and substituted by Blackwood. "He came this morning and I don't know if it was because of the heat or what - you know - he was feeling a little bit dizzy. He had a headache, so we took the precautionary route and pulled him off", Holder said.

Blackwood, not a part of the original squad for the Kingston Test, scored 38 in what was his first Test since October 2017, when he played Zimbabwe at Bulawayo. Much like Australia's Labuschagne, who took Smith's place after the latter faced late concussion symptoms, Blackwood's place in the side was confirmed a day after Bravo first got hit.

The concussion substitution rule came into effect from August 1 this year, keeping in mind multiple instances of batsmen retiring hurt and failing to recover, leading to a loss for their side. Thus, the ICC has allowed a like-for-like replacement for the same.
