Liverpool sweating over scary Alisson head injury on Brazil duty | OneFootball

Liverpool goalkeeper Alisson will be sent for scans on Friday after suffering a sickening head injury during Brazil's 2-1 victory over Colombia.

Midway through the second half, a gruesome collision with Colombia defender Davinson Sanchez left both players down on the turf. Sanchez was ultimately stretchered off the field and Alisson was also substituted.

After the game, Brazil's team doctor confirmed Alisson did not lose consciousness but had suffered a suspected concussion.

"Alisson suffered a head injury," doctor Rodrigo Lasmar revealed. "He was replaced due to a suspected concussion, so now we will follow the protocol recommended by the CBF.

"He will undergo the recommended imaging tests. First, we will perform a CT scan, followed by a diffusion MRI. If all the tests are negative and normal, we will then perform a cognitive test, and then we will evaluate the player. If everything is normal, we will conduct a series of observation tests over the next few days to see whether or not he would be able to travel with us and go to Argentina for our next game.

"The first step is to perform the necessary tests and assessments and monitor the player over the next few days, which is the protocol. Alisson is normal. I believe you saw the images of him on the bench and after the game. He is completely normal now, without any complaints.

"During the treatment on the field, he did not report any fainting or memory loss, he was conscious and oriented the whole time. We substituted him because he had minor complaints, he thought he was a little slower and there was some possibility of a concussion, so in cases of this suspicion, the recommendation is to substitute the player."

Alisson is now doubtful for Brazil's high-profile clash with Argentina on Tuesday evening, while Liverpool officials will also be eagerly awaiting an update on their starting goalkeeper as they prepare to return to Premier League action with a Merseyside derby against Everton on April 2.

Premier League rules state any player diagnosed with a concussion must spend at least two weeks on the sidelines to ensure they have fully recovered, meaning Alisson would not be cleared to return until two days after the Everton fixture.
