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, according to reports.

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 reported that Karius has since been examined by a specialist while on holiday in the United States.

Karius flew to the US on holiday after the final and, with Liverpool determined to safeguard the player’s well-being, he visited the specialist Dr Ross Zafonte at the Massachusetts General Hospital in Boston.

It is understood Karius has continued his holiday Stateside and will return to Liverpool for pre-season training on July 2, although Jurgen Klopp’s side have been strongly linked with signing a new goalkeeper next season.
