The youngster came into the club on the recommendation of coach Enzo Maresca.
The two worked together at Leicester City in the Championship last term.
However, Dewsbury-Hall has not been able to get into the team and is surplus to requirements.
Per The Mirror, he is being told by Chelsea that he can find a loan club for himself.
The club will help him find a situation where he is playing regularly for the rest of the season.
If he is to be sold permanently, Chelsea want to recoup around £30 million.
