Ahead of their first group stage match versus Gladbach last week, which was drew 2-2, the Moroccan was forced to miss out after receiving a positive coronavirus test.
After that test proved to be false, and a subsequent negative test was confirmed, he made his return off the bench against Genoa.
Milan Skriniar and Roberto Gagliardini, however, are still in isolation after contracting the virus.
Matias Vecino still has a knee injury.
Alexis Sanchez was replaced at half-time in the draw against Gladbach and didn't play against Genoa, either, and with Stefano Sensi also injured that could mean a start for Christian Eriksen behind strikers Lautaro Martinez and Romelu Lukaku.
Inter's star performer versus Genoa was Andrea Ranocchia, who earned a 9.6 FC Rating for his performance, so has put himself into real contention for a start in the back three.
