Manchester City goalkeeper Ederson has joined the drive for concussion substitutions after seeing the horror collision between Raul Jimenez and David Luiz at the weekend.
David Luiz continued playing after having his head bandaged, but the defender was substituted at half-time after his cut began to bleed again.
The incident has amplified focus on the risk of lasting head trauma to footballers amid a campaign in England for the game's authorities to take greater steps to reduce the danger of later-life health problems such as dementia.
While Arsenal boss Mikel Arteta insisted David Luiz was cleared to continue after adhering to concussion protocols, Alan Shearer, the Premier League's record goalscorer, insisted more must be done to safeguard players from serious head injury.
"Football needs to get real, it needs to wake up, it needs to get serious. Not next year, next month, now. It is not acceptable, it has been going too far too long," Shearer, who has previously presented a documentary on dementia, said on BBC's Match of the Day.
Ederson, a former team-mate of Jimenez at Benfica, told reporters on Monday: "I was very worried. I was watching the game. It was an accidental clash, head to head but very difficult.
"All the concern and all the care at the moment is very important. It is a part of the body that is very fragile and needs special attention, I agree when there is a blow to the head there should be a substitution whether the player can continue or not because you might be feeling okay because you're warmed up, but after the game you could feel the consequences.
"It is something we cannot change, it is accidental. It wasn't an intentional blow they just went to compete for the ball, but we know the risks of a head injury. I hope he recovers quickly and will be back as soon as possible."
Jimenez will not be available in time for Wolves' next outing away at Liverpool in the Premier League on Sunday as he remains in observation in hospital over the next few days.
Meanwhile, Ederson will be back in action with City on Tuesday when Pep Guardiola takes his side to Estadio do Dragao to face Porto in the Champions League, and Luiz is currently preparing with the rest of the Arsenal squad ahead of a Europa League meeting with Rapid Vienna on Thursday.
