British number two Greg Rusedski said today he was "cautiously optimistic" about the outcome of his drugs hearing in Montreal.
Rusedski flew into London from Canada and spoke for the first time since yesterday's hearing about the drugs test he failed last July.
"I'm confident and we'll just have to wait and see," Rusedski said. "We're cautiously optimistic so we are just hoping for the best."
The 30-year-old tested positive for the banned steroid nandrolone during a tournament in Indianapolis in July.
Rusedski, who has denied knowingly taking performance-enhancing drugs, went before a three-man panel in Montreal.
If found guilty, the 1997 US Open finalist faces a two-year ban which would effectively end his career.
"I have no idea when I'm going to hear the verdict. It's anywhere between three to nine days. So all I can do is sit tight at the moment," the player said.
