Four of the Bulls loanees have returned to their parent clubs, Hereford United have announced.
Daniel Preston, Jake Jervis, and Lewis Young have all seen their loans expire, while Paul Downing has been recalled by West Brom.
Preston played four times for the Bulls, but had spent the past month warming the bench, while fellow Birmingham loanee Jervis made five starts and two sub appearances, scoring twice.
Young returns to Watford after five starts and one sub appearance while Downing, who has been rarely even named as an unused sub since being sent off at Notts County at the end of February, made six appearances.
Meanwhile Lee Morris has extended his loan at Forest Green until the end of their season on Saturday. He has scored twice in one start and seven sub appearances as they fight against relegation. He will be available for the Bulls final two games of the season with the Conference season ending earlier than the Football League.
