Amavi suffered an injury during the France Under-21 side’s game against their Northern Ireland counterparts.
The 21-year-old defender landed awkwardly, hurt his right knee and had to be taken off rightaway.
Gardner, who is himself injured at the moment, hopes that the left-back’s problem is not too bad.
