Adverse events of variable severity may occur occasionally following whole blood donation. We are reporting a case of severe donor reaction leading to grievous injury. A first-time male voluntary blood donor donated blood in our blood donation camp. The donation was uneventful, and he left the premise after 20 min of postdonation observation and advice. Several minutes later, he fell on the road and injured himself complicated with severe delayed vaso-vagal reaction. The donor had lacerated wound over the chin, fracture neck of the left mandible, fracture left lower incisor and left lower molar tooth. Appropriate medical care was catered to the donor with full medical support from Department of Transfusion Medicine and was fully recovered from the injury. Blood collection team must take up the responsibility of the management of all complications related to blood donation.
