The incident occurred in the first half
Raul Jimenez is conscious and responding well to treatment after suffering a serious head injury, according to Sky Sports.
The Wolves striker went down injured after clashing heads with Arsenal defender David Luiz while jumping for the ball at a corner. As he dropped to the floor, the Mexican appeared to be unconscious as medical staff tended to him.
An oxygen mask was placed on Jimenez's face before he was carried off the field and taken to hospital.
In the second half, Sky commentator Bill Leslie told viewers Jimenez had regained consciousness again and was responding to treatment.

Controversially, David Luiz was allowed to continue playing with a bandage on his head, having emerged from the clash in a less serious condition than Jimenez. Many viewers objected, claiming the Premier League rules should stipulate that he is also made to be substituted to mitigate the chance of worsening a serious concussion.
Luiz was eventually replaced by Rob Holding at half time.
