Liverpool striker Rhian Brewster was hauled off the U23 pitch yesterday after just 15 minutes.
The Mirror says Brewster was substituted after just 15 minutes of Liverpool under 23s clash with Derby in response to Divock Origi's injury.
Belgium international Origi was forced out of the first team's lunchtime victory over Newcastle with an ankle issue.
While Origi limped off in the 37th minute at Anfield, Neil Critchley had already named Brewster in his starting XI for the youth side on the other side of Liverpool for the 3pm kick off.
A message was sent to Melwood soon after to take Brewster off as a precaution ahead of the Reds' Champions League opener with Napoli on Tuesday.
Origi will undergo a scan in the next few days, but while Jurgen Klopp waits for the results he is ready to promoted 19-year-old Brewster to the travelling squad to Italy.
