Wolves striker Raul Jimenez has had surgery on a fractured skull suffered in a clash of heads during his side's Premier League win at Arsenal.

Sunday's match at Emirates Stadium was in its early stages when Jimenez and Gunners defender David Luiz accidently collided at an Arsenal corner.

He was given oxygen on the pitch before being taken to hospital.

"Raul is comfortable following an operation last night," Wolves said in a statement.

"He has since seen his partner Daniela and is now resting. He will remain under observation for a few days while he begins his recovery.

"The club would like to thank the medical staff at Arsenal, the NHS paramedics, hospital staff and surgeons who, through their skill and early response, were of such help."

The game was stopped for around 10 minutes to allow Jimenez, 29, to receive treatment before he was carried off the pitch on a stretcher.

"You start hearing 'code red'," Wolves boss Nuno Espirito Santo said.

"It was a bad moment. What was the reaction? Panic, panic panic. You could see the faces on the team-mates. It was a serious situation. It's awful and terrible."

David Luiz was able to continue after receiving treatment following a clash of heads with Raul Jimenez during the Premier League match between Arsenal and Wolves

Raul Jimenez was replaced by Fabio Silva after being carried off on a stretcher at Emirates Stadium.

Nuno's Arsenal counterpart Mikel Arteta said he knew "something really bad is happening" from the reaction of the players.

Brazil centre-back Luiz, 33, played on with a bandage wrapped around his head before being substituted at half-time.

Speaking on Match of the Day 2 about the decision to allow Luiz to continue playing, former England striker Alan Shearer said: "Football needs to get real and wake up. It needs to get serious, not next month, now. This has been going on for far too long. The [concussion] protocols in football are not acceptable."

Jimenez scored 17 goals as Wolves finished seventh in the Premier League last season.

He had netted four times in nine top-flight appearances this term before Sunday's match and signed a new four-year contract with the Molineux club in October.

Wolves captain Conor Coady: "We were massively worried when it happened. We knew straight away it was a horrible clash of heads.

"But we just hope and pray everything is OK because it's something we never want to see.

"He is with the right people now and that's the most important thing. He is in hospital and, by all accounts, he is awake and breathing."

Arsenal manager Mikel Arteta: "I was shocked because I saw the reaction of the players - they were asking the doctors. We were really worried for Raul Jimenez because it was really nasty."

Wolves forward Pedro Neto: "I was a little bit worried. I didn't see the impact but I heard it. I hope he is OK and can recover to come back with us."

Arsenal midfielder Joe Willock: "On behalf of the club and myself, we give our best regards to Raul Jimenez. We hope he recovers well. It was a bad incident. David Luiz has recovered well. He looked good when I saw him in dressing room."

Luiz decision raises concussion questions
Arsenal said protocols were followed regarding the decision to allow Luiz to play on after the incident.

However, the Brazilian was pictured with blood seeping from his head bandage and did not reappear for the start of the second half as he was replaced by Rob Holding.

Footballers who sustain a suspected concussion, either during training or in a game, should immediately be removed from the pitch and not allowed to return until the appropriate treatment has been administered, according to FA guidelines.

Arsenal said protocols were followed regarding David Luiz returning to play.

Arteta said afterwards: "We followed the protocol to check he [Luiz] had not lost any consciousness, which he hadn't, and then some tests.

"They will continue to do some more checks on him. He was really uncomfortable and couldn't really head the ball and couldn't continue."

Shearer said action must be taken immediately to review concussion protocols to protect players.

Shearer has previously presented a BBC documentary on dementia and is aware of the risks players face from head injuries.

"If David Luiz has passed all the protocols like Arsenal say he has, how on earth is he allowed back on to the pitch with a wound that is dripping down his face?

"We're talking about players' welfare here. Football's protocols allow someone who has a cut that is seeping through a bandage that has just been put on to carry on playing and then he has to go off again 20 minutes later because he can't head a ball.

"Cricket do it, the NFL does it, both codes of rugby do it - they all have better protocols. We're talking about life and death and players' careers ending.

"They're on about trialling concussion substitutes. What is there to trial? It's been going on for years. It's not acceptable.

"We've been having meeting after meeting after meeting. Why do they need to trial anything? Just do it. Do it now. If things needs changing after that, change it."

Luiz na confirm Coconut head

TochiOlisa:
The Arsenal doctors should be suspended for certifying Luiz ok to continue after that kind of head clash. I heard the clash loudly and I was just watching from the TV. What they saw and heard I have no idea.
Head injuries in sport is not a small matter. Check retired boxers and pro footballers. They'll tell you what they're going through as a result of suffering repeated blunt trauma to the head over the years. It's no joking matter
