West Indies batsman Nkrumah Bonner has been subbed out of the first Test against Australia with concussion after copping a nasty blow to the helmet.
Bonner was struck on the side of the helmet while trying to evade a 139.5km/h delivery from Cameron Green during the morning session of day three at Optus Stadium.
The 33-year-old received on-field treatment for five minutes and batted on for another half an hour before retiring hurt on 16.
The West Indies were initially hopeful he would be able to return, but they later ruled him out and replaced him with Shamarh Brooks as a concussion substitute.
It's been a painful Test for the West Indies batters, with the Australian pace attack peppering their opponents on numerous occasions.
Debutant opener Tagenarine Chanderpaul copped a painful blow to the testicles from a seaming Josh Hazlewood delivery on Thursday.
Chanderpaul was also struck several times on the body during his knock of 51.
Jermaine Blackwood has been struck several times on the gloves while trying to evade rising deliveries, while captain Kraigg Brathwaite (64) also copped some punishment.
