Former Wales international and Dragons centre Jamie Roberts expressed displeasure after his Covid-19 test result was made public.
The 33-year-old, who joined Dragons from Super Rugby club Stormers was tested positive for novel coronavirus and was isolated from the rest of the squad members along with his close contacts.
Roberts was only player to have tested positive with the Welsh Rugby Union revealing that 288 other tests returned negative for Covid-19 which meant the 6ft 4in centre will be forced to miss the club's first Pro14 game since the suspension in March against Ospreys on Sunday.
"Appreciate messages re. Covid. I'm feeling fine. Lot of DIY at home," Roberts posted on his social media account Twitter.
"Delighted no other positive tests and Welsh derby matches get (thumbs up emoji).
"How was my confidential medical information published? How's that Editors code of conduct treating you?"
Earlier, Dragons confirmed that a player from the club was tested positive but did not reveal the name.
"Dragons Rugby has returned a positive case for COVID-19 in Welsh Rugby’s testing programme in the round of tests taken week commencing Monday, August 10," read a statement from Dragons.
"All subsequent Public Health Wales and Government guidelines are being followed and the individual – who is symptom free and in good health – is currently isolating.
"Dragons Rugby is part of the wider Welsh Rugby Union screening programme which has conducted over 1,100 tests to date as part of the return to training/ playing process.
"This is a confidential and private health matter and we will make no further comment."
Roberts has played 94 Tests for Wales and an additional three for the British and Irish Lions. He also has experience of playing for Cardiff Blues, Racing 92, Harlequins, Bath and Stormers since his professional rugby debut in 2005.
