Chelsea's £58million signing Romeo Lavia was injured on his club debut against Crystal Palace on Wednesday - after spending four months on the sidelines with a separate ankle issue.
Lavia played the final 32 minutes of Chelsea's 2-1 win over the Eagles at Stamford Bridge after a long wait for his first team bow - having been injured since arriving from Southampton in the summer.
It should have been a moment to savour for Lavia after he finally got a run-out for the Blues having replaced Ian Maatsen just before the hour mark - but it was one that quickly turned into a nightmare after news he had suffered a set-back after leaving the pitch.
