What are the Premier League concussion rules?
Liverpool v Tottenham (Sun, 16:30 GMT)
Ask Me Anything
Tottenham will be without Cristian Romero and Joao Palhinha as they follow Premier League's concussion rules after a clash of heads against Atletico Madrid in the midweek.
The FA has strict procedures on dealing with head injuries and the guidelines for dealing with possible concussion operate under the tagline of 'if in doubt sit them out'.
It means that if a player has suspected concussion at any level of football "they must be immediately removed from the pitch, whether in training or match play".
If a player is judged to be concussed, they should be supervised for 24 hours and begin a six-stage 'return to play' process. This starts with an initial 48-hour period of rest with minimal physical and 'cognitive' activities, such as working and using screens.
The FA then recommends "a staged and graduated return to full daily activities", where "football training is allowed, but at a rate that does not worsen existing symptoms more than mildly or produce new symptoms".
The second stage allows light exercise, followed by the final four stages of football-specific exercise, non-contact training, full-contact training, and finally a full return to play.

Analysis - Tudor comes out fighting
Liverpool v Tottenham (Sun, 16:30 GMT)

Igor Tudor has come out fighting at Tottenhamâs training ground.
The Croat is facing the sack after four defeats from his four matches in charge, but he isnât feeling sorry for himself and has urged his players to follow suit.
Heâs told his players not to think the world is against them â nor to believe that they are somehow cursed by âblack magicâ.
âDonât act like the victim,â was the overriding message. But that is easier said than done, of course, particularly considering their extensive injury list that has worsened now with Cristian Romero and Joao Palhinha to miss the game with concussion.
That, coupled with the absence of Micky van de Ven through suspension, means Tottenham are likely to have Kevin Danso and Radu Dragusin at the heart of their defence at Liverpool on Sunday.
So if the Tottenham players are feeling down in the dumps, then it is understandable.
Regardless, Tudor isnât standing for it and has challenged his players to stand up and be counted in their fight against relegation.

Tottenham Hotspur
Tottenham manager Igor Tudor was asked who is finding the current situation the most difficult: "Everyone is finding it difficult. If you want to find it difficult and find challenges. To give this in measures of one, two or three, that is not the point.
"Like is life. In life you can be happy with the small things or be unhappy and have almost everything. Life is about what is enough for you, you choose that. Football is also part of life. How you see the situation? You choose."

Igor Tudor was asked if Guglielmo Vicario was dropped for the Atletico Madrid game, which Antonin Kinsky started but was subbed off for Vicario in the 17th minute: "The idea was to make him [Antonin Kinsky] play because first of all he is a good goalkeeper and being in this situation, in this period, to give some freshness in the goal in a different competition The idea was to start him but after what happened of course it is a little bit different."
Will Vicario come back in against Liverpool?: "He is good. He will be in the goal."

More from Tottenham manager Igor Tudor on whether he has any hesitation about playing Antonin Kinsky moving forwards, after substituting the 22-year-old goalkeeper after 17 minutes in Tuesday's defeat at Atletico Madrid: "He will play for sure. He came back the day after and was very good and positive in training. Nothing else. This is probably the first and last time that this happened in my life and the life of a lot of people.
"It is the same message that I had before. You can go out and be the victim - everyone was sending messages of help and 'I am with you' and this is nice also.
"But, sometimes, in 2025 in this social media life - it is more important what you say than what you do. But, as I said before, this is a mistake, he will be for sure in his career - make other mistakes - but I think he has the strength and quality in front of him to have a very good career."

Tottenham manager Igor Tudor on team news and whether Joao Palhinha and Cristian Romero can play after clashing heads in midweek: "No, no. They are out. Micky [van de Ven] is also out. [Yves] Bissouma is out with a muscle [injury]. Conor [Gallagher] has some fever, but probably will be in.
"We have a lot of problems to make first eleven. This is how it is at this club. It happens all the time. We start to build something and then something happens like a red card in the last game or three or four injuries.
"It is very rare, I have never had this situation in my career where you have two players missing every game. It is very unusual but you have to accept this and try and change the things we can change. These things we cannot."
'You can cry or you can fight'

Tottenham Hotspur
Tottenham manager Igor Tudor on the situation the club find themselves in: "Tough. For sure. Not just because of the last game but because of the period. Not easy situation, not easy moment. Big challenge to change things. Like everything in life, you can choose how to see the situation.
"You can cry or you can fight. You can be the victim or you can say I can change something and this is the message I want to start with and what I communicate with the players. Everyone speaks and everyone has opinions. The bottle is always half empty or half full. Here, there is nothing full, there are a lot of empty things but difficult moments don't last.
"I believe the players will take this as a challenge, as an opportunity, to stand up with the courage to change things after this period."
No shortage of talking points as Tudor faces media

It's been another week from hell for Tottenham and Igor Tudor.
Youâd forgive the Croat for, the very least, wondering if taking this job was worth it.
A 100% loss record since taking over from sacked Thomas Frank has the Spurs board fearing they have made a grave error of judgement in appointing Tudor in the first place.
Added to that, as BBC Sport reported on Tuesday, a growing disconnect between the manager and the Tottenham squad has left the club in what appears a state of crisis.
Thatâs before we even mention the narrative regarding his treatment or Antonin Kinsky, who was subbed off after just 17 minutes of his Champions League debut on Tuesday night.
That said, unless a drastic turn of events occur over the next 48 hours, Tudor will remain in charge for Sundayâs clash against Liverpool.
Tudor faces the media ahead of that trip to Anfield this weekend later this afternoon. There wonât be a shortage of talking points.
