Chuks Aneke is out for the rest of the season with a hamstring injury: https://londonnewsonline.co.uk/charlton-athletic-striker-chuks-aneke-set-to-miss-remainder-of-league-one-season/
It is difficult to recall such an injury prone player.
Whilst I have every sympathy for Chucks. It's clear he has serious and repetitive injury problem with the hamstrings. Playing no more until the start of next season is probably best for him. It would probably be best for Charlton if Chuks retired and they claimed on the insurance.
