The allegation is contained in a statement of grounds released by the AFL on Wednesday, outlining the basis of charges the league has laid against the Bombers, Hird and three other Bombers officials over the club's 2012 supplements program, which is still under investigation by the Australian Sports Anti-Doping Authority.
The charges, of bringing the game into disrepute, were due to be heard by the AFL Commission on August 26, but all parties have sought more time and AFL chief executive Andrew Demetriou says a new date is yet to be determined.
The AFL notes the statement of grounds are charges only, with their correctness or otherwise still to be determined.
In them, the league said the Bombers either allowed players to be administered substances that were prohibited by the AFL Anti-Doping Code and the World Anti-Doping Code, or, alternatively, the club was unable to determine whether players were administered substances prohibited by the two codes.
It also lists a string of failings by the club, including that the Bombers:
* exposed their players to significant health and safety risks.
* disregarded standard practices involving the human resources department when employing high performance manager Robinson and sports scientist Stephen Dank, two key figures in last year's supplements program, both of whom have since left the club.
* failed to devise or implement any adequate system or process to ensure that all substances provided to and used by players were safe and were compliant with the AFL Anti-Doping Code and the World Anti-Doping Code.
It also details how the AFL believes Hird, his assistant Mark Thompson, football manager Danny Corcoran and doctor Bruce Reid failed in their duties.
It contains in full a letter from Reid to Hird and then-football manager Paul Hamilton in January 2012 expressing Reid's concerns about the supplement program.
In the letter, Reid said he had "fundamental problems being club doctor at present", as players had been receiving injections of AOD-9604 without his knowledge.
He described the use of the drug as "ludicrous", said the fact that it was marketed for body builders should "raise a red flag" and questioned whether Hird or Hamilton would want their children injected with it.
A protocol was subsequently established under which Reid would have to be fully informed and give his approval before supplements were administered to players.
But it is alleged that numerous other substances were subsequently given to players without that protocol being followed, or any form of approval being given by Reid.
Also, Hird is alleged to have received vials of Melanotan II and syringes from Robinson in or about October 2011, with Robinson instructing Hird how to self-administer the substance.
Hird was never warned about potential adverse reactions, but suffered "significant side effects", the AFL says.
During 2012, Hird received "amino acid and multi vitamin" injections from Dank, in Dank's office, which it is alleged was not clean or hygienic enough to make it an appropriate venue.
The AFL alleges Dank did not inquire about Hird's medical history or warn him of potential side effects.
And Dank also failed to make the same inquiries or warnings when he administered Hird tablets likely to have been Ephedrine and Propranolol during 2012.
Despite Dank and Robinson failing to keep records or take appropriate safeguards when supplying him with substances, Hird never questioned whether they were administering Bombers players supplements with the same lack of appropriate protocols, the AFL says.
The AFL also alleges that Hird was interviewed by representatives of ASADA and the AFL's integrity unit in August 2011, after making an inquiry about peptides.
He was told peptides were a serious risk to the AFL's integrity, in the same category as steroids and HGH and told to report to the AFL if he came across any information relating to peptides.
Danny Corcoran, who was then the Bombers' people and development manager and is now football manager, and then-football manager Hamilton were both present at the meeting.
