Since David Luiz and Raul Jimenez battled in the early stages, Arsenal and Wolves’ clash at the Emirates was brought to a halt.
The guy of the Wolf came out much weaker, getting stretched off the pitch by a wealth of medics reviewing his condition.
After a few minutes, Luiz got up, but as blood spilled down his face, he was a mess.
Before heading out to the pitch for Arsenal, the Brazilian was bandaged up on the touchline.
As his team-mates looked on in horror as the Mexican lied on the Emirates turf unmoved, Fabio Silva substituted Jimenez for Wolves.
The two men collided heads after Willian’s corner diving for a header, with other players quickly noticing that after the loud noise that echoed across the empty stadium, something was wrong.
Captain Conor Coady of the Wolves and goalie Rui Patricio promptly called the bench for medical assistance.
After being strapped up, Luiz eventually rose to his feet and the defender went straight over to see if his counterpart was all right.
An update on Jimenez was quickly provided by Sky Sports, confirming that the Wolves man had been taken straight to the hospital.
Even the station declined to screen a repeat of the case.
But there was concern among fans that after the heavy clash, Luiz was permitted to proceed.
Nevertheless, the Arsenal man went on and had his side surrender the first goal in the first minute.
Pedro Neto scored just before the half-hour break, following up after Leander Dendoncker’s header crashed off the crossbar.
Soon after, however, Wolves conceded, with their lead only lasting about three minutes.
After 30 minutes, Gabriel Magalhaes went home to score his first Emirates goal, helped by Willian’s pretty cross.
With an expertly taken goal by Daniel Podence to make it 2-1 to Wolves at half time, the visitors then reclaimed the lead.
Before his departure, injury-stricken Jimenez was making his 11th start of the season for Wolves.
Since arriving in England two years ago, the 29-year-old has established himself as one of the top Premier League strikers.
A report from Sky Sports in the second half explained that Jimenez was mindful of and adjusting to treatment in the hospital.
Luiz meanwhile was eventually replaced at halftime by Mikel Arteta.
Wolves kept on to win 2-1, and after the game, the club wrote on Twitter: “Raul’s head injury is being assessed with a scan at a London hospital.”
Wolves manager Nuno Espirito Santo told Sky Sports to fix Jimenez’s condition: “Raul Jimenez is doing a scan now He’s conscious. He’s OK inside the gravity of the problem.”
What it was like at the time: “You start hearing the red code. It’s serious. For everyone, it was a bad moment.”
In their [medical staff] eyes, you see fear and you start thinking, how is he? We are scared.
“He speaks, he’s aware. We have to have a proper assessment. He’s in good hands.”
