AFL doctor takes jab at treatment

The medical officer advising the AFL Players Association says there is little need for players to be injected with supplements, and is hopeful ''regulatory sanity'' is restored over what products are administered to players.

As Essendon maintained everything their players were injected with last year complied with anti-doping rules, Dr Andrew Daff queried why players should need to be injected with products such as vitamins and other supplements in the first place.

''One would think if we've got players who are being regulated really well with regards to their [training] loads and their nutrition; that it would be very rare to have someone with a deficiency that would need supplementing,'' Daff told 3AW.

''Sometimes these things are done a little bit [by] blanket [coverage], maybe a bit unnecessary. We've all the heard the term 'the most expensive urine', meaning the same components being supplemented are being excreted as urine into the toilet.''

Daff, also a long-serving medical officer at Melbourne, said during his time with the Demons it was ''very rare'' to have to inject players with vitamins. But he said there was no need to ban injections completely, as players occasionally needed to be treated intravenously with antibiotics or in serious cases of dehydration.
