Hughes was responding to a report in the Daily Mail newspaper that the Burundi-born 23-year-old had tested positive out of competition in September for a recreational drug.
As it was a recreational drug the forward tested positive for, he wasn't subject to the World Anti-Doping Agency sanctions. The trouble is there seems no discernible advantage for them in what looks like being a very evenly-contested encounter and a point each seems an obvious conclusion to draw. Pulis suggested he was overweight and Berahino, rather unwisely, took exception to the accusation publicly.
At that time, there were claims the striker was struggling with weight issues, while manager Tony Pulis admitted the striker needed to "get his act together".
"Anything Stoke asked for, we told them the truth".
"But it shows the depth and quality of the people in this football club that they have tried to protect one of their own".
"I wish him all the best. On that basis, he has served his suspension".
Hughes confirmed his knowledge of the ban but did not elaborate on the circumstances.
Hughes would not confirm why Berahino was suspended, but said Stoke had been aware of the matter prior to completing their £12 million ($15 million, 13.9 million euros) move for the striker.
Stoke boss Hughes has played down the seriousness of the latest incident.
'It was an FA disciplinary matter. I think this club has been open and honest in everything it's done concerning Saido. As with all players we did our research on him before we signed him, but that didn't change our thinking at all. "It's out there - they [Berahino's camp] didn't try to hide it". "You try to have an insight into what actually went on", he said.
The FA does not comment on its social drugs policy regulations and a spokesman had nothing to add. It was no shock to hear Tony Pulis whining about West Brom's game at Middlesbrough clashing with the final day of the transfer window but his assessment was accurate in terms of them having more than enough chances to win the game and keep the Baggies within hailing distance of the top six.
The teams played to a 1-1 draw at bet365 Stadium in the reverse fixture September 24 as Salomon Rondon's stoppage-time goal canceled out Joe Allen's marker on 73 minutes. One, that he wasn't fit and, two, that he was serving an FA ban.
