Wolves recovered from losing top scorer Raul Jimenez to a sickening head injury to inflict Arsenal's third consecutive home league defeat with a 2-1 win at the Emirates on Sunday.
The Mexican received treatment from medics for 10 minutes on the floor after colliding with David Luiz before being stretchered from the field.
Luiz continued with blood seeping into a white bandage wrapped around his head until half-time, when he was replaced by Rob Holding, leading to fresh calls for the introduction of concussion substitutes in football.
The rest of the Wolves team had combined for just five goals in their previous nine league games, but Pedro Neto and Daniel Podence struck to hand the visitors a first win away to Arsenal since 1979.
Sky Sports reported Jimenez is conscious in hospital and responding to treatment.
