Wolves striker Raul Jimenez was substituted after suffering an apparently severe head injury during Sunday's Premier League game at Arsenal.
Jimenez was helping his team defend a corner four-and-a-half minutes into the match at Emirates Stadium when he suffered a sickening clash of heads with Gunners defender David Luiz, who was attacking Willian's right-wing corner.
David Luiz was able to continue after having his head bandaged and undergoing concussion protocols, but Jimenez was treated for almost 10 minutes on the turf before being taken from the field on a stretcher.
He appeared to be unconscious after the impact and received oxygen from medical staff while on the pitch.
The 29-year-old Mexico international, who was taken straight to hospital, had four goals in nine Premier League appearances this season ahead of this weekend. He has been directly involved in 27 top-flight goals (21 goals and six assists) since the start of last season.
Wolves' record signing Fabio Silva was introduced in place of Jimenez, and the game was 1-1 before the half hour, with Arsenal defender Gabriel swiftly cancelling out Pedro Neto's opener.
