AC Milan have growing injury concerns for Divock Origi.

The former Liverpool striker will miss the upcoming games against Dinamo Zagreb and Napoli.

The 27-year-old's injury initially seemed to be localised in his thigh muscles, but now indications suggest that the root of the issue is deeper and is related to his tendons, more serious than first predicted.

Calciomercato.com says Origi is flying to Belgium to be treated by national team doctors. They also monitored Origi over the summer.

It's been revealed after every two or three training sessions Origi is forced to rest in order to avoid overloading his muscles.
