BOSTON/LIVERPOOL: Loris Karius has been diagnosed as having suffered concussion during Liverpool’s 3-1 Champions League Final against Real Madrid in Kiev.

The 24-year-old was at fault for the Spanish side’s first and third goals and was sent for tests at hospitals in Boston in the United States.

Dr Ross Zafonte said it was “possible” the injury “would affect performance”. He assessed Karius as having suffered from “visual spatial dysfunction” which could have affected his ability to judge objects in terms of time and space.

Karius collided with Real defender Sergio Ramos early in the second half of the final – when the score was goalless – although doctors have not pinpointed the moment he was concussed.

Minutes after that collision, Karius threw the ball against Real striker Karim Benzema, and it rolled home to give the Spaniards the lead. Liverpool equalised through Sadio Mane, but Gareth Bale scored a stunning overhead kick then netted Real’s third when Karius let a shot from long range slip through his hands.
