QPR defender Damion Stewart will see a neurosurgeon on Saturday night after suffering a cracked skull against Crystal Palace.
The Jamaican defender was stretchered off in the opening seconds of Rangers' 2-0 win at Selhurst Park after a sickening clash of heads with Eagles striker Calvin Andrew.
"They've detected a slight crack in his skull and there is bleeding around it," said Rangers manager Neil Warnock.
"The neurosurgeon on his way and they are very concerned about him. It was a savage collision."
