Liverpool goalkeeper Loris Karius underwent a post-Champions League final scan amid concerns that he had suffered a head trauma following a collision with Sergio Ramos.
Karius was badly at fault for two of the three Real Madrid goals as Liverpool lost 3-1 in Kiev on May 26.
But the German goalkeeper was floored by Ramos while defending a corner prior to Madrid's first goal, and Liverpool's medical team were concerned about the possibility of Karius suffering a concussion.
Liverpool have declined to comment, but it is understood Karius has since been examined by a specialist while on holiday in the United States.
