Kudus Mohammed Champions League debut against Liverpool came to a disappointing end after suffering an injury early in the game.
Fresh from scoring his debut goal for the Dutch giants over the weekend, the 20-year-old went down in the six-minute, clutching his right leg after a clash with Liverpool Fabinho.
After three minutes of on-pitch treatment, it became apparent that his time in the Group D matchday one fixture had ended as he walked off the pitch, his place taken by Quincy Promes.
It is yet to be known the full extent of the injury and how long Kudus will be kept on the sidelines.
Premier League champions Liverpool were helped by an own goal from Nicolas Tagliafico to get off to a winning start in the Champions League against Ajax.
Jurgen Klopp’s injury-hit side, who were without talisman Virgil van Dijk, were tested by Ajax but did enough to leave Amsterdam with a clean sheet.
Tagliafico sliced Sadio Mane’s cross into his own net with 10 minutes of the first half remaining, moments after Liverpool keeper Adrian denied Quincy Promes from close range.
Liverpool’s Fabinho then acrobatically cleared Dusan Tadic’s lob off the line, before Davy Klaassen’s powerful effort bounced off the inside of the post in the second half.
The Reds, who also face Atalanta and Midtjylland in Group D, were returning to Europe as English champions for the first time since 1984-85.
