As per concussion return protocols, Fofana was required to sit out for 12 days, which has now been completed. He has resumed training and is expected to be available for Chelsea's next Premier League game against Nottingham Forest.
The team's defensive rotation has taken a hit with Fofana's absence, as well as injuries to other key defenders, including Benoit Badiashile, Trevoh Chalobah, and Levi Colwill. However, with Fofana's return, the team's defensive situation is improving.
The upcoming game against Nottingham Forest, managed by Ange Postecoglou, may appear to be an easy win for Chelsea. However, with a portion of the international break still remaining, there is a risk of other injuries occurring that could impact the team's lineup.
