Irish internationals Ronan O'Gara and David Wallace have come out in support of their colleague, Frankie Sheahan, in his dispute with international rugby officials.
Sheahan was suspended for two years earlier this year after testing positive for salbutamol, a banned substance. The Munster player claimed the drug entered his system through his asthma inhaler.
O'Gara and Wallace, who are also asthmatics, have joined Sheahan in his battle to have the two-year ban overturned.
