It's been confirmed Liverpool goalkeeper Loris Karius suffered concussion during their Champions League final defeat to Real Madrid.

Massachusetts General Hospital has confirmed the findings.

The Liverpool goalkeeper underwent head scans over the weekend amid scares he suffered a trauma during the defeat to Real Madrid.

Sergio Ramos crashed into Karius during the encounter in Kiev, with the German goalkeeper receiving a heavy blow to the head.

Just minutes later, Karius was guilty of a shocking error as his attempted throw rebounded off Karim Benzema and into the net. And later in the clash he failed to keep out Gareth Bale's long-range effort.

Liverpool's medical staff were concerned that Karius could have been suffering with concussion and he was sent to visit trauma specialist Dr Ross Zafonte during a holiday to the United States, says the Mirror.

A statement from Dr. Ross Zafonte claimed Karius suffered "visual spatial dysfunction" after the incident and such deficits would have affected his performance.

Karius' condition is said to have improved since the event and the German will make a full recovery if the correct protocol is followed.
