The Hereford defender needs the injection to combat chronic tendonitis in his Achilles.
Green, who is set to have his jab tomorrow afternoon, has commented:
"I would just like to say a huge thank you to everyone at HUST and Hereford Away Days and anyone else who has been kind enough to donate to my treatment. I am truly overwhelmed by the support and kind comments.
"The support I have received from you guys from the first day I signed for Hereford has been unbelievable and I am truly grateful."
