Greg Rusedski is set to discover the result of the hearing into his positive drugs test within the next few days.
Greg Rusedski could be banned for two years
Rusedski, who tested positive for the anabolic steroid nandralone, has been waiting for the result for a month and continues to protest his innocence.
If Rusedski is found guilty he faces a two-year suspension and potentially the end of his career.
However, David Felgate, the Lawn Tennis Association's performance director, believes British tennis could cope.
"If the worst happens, we will be able to handle it," said Felgate.
Great Britain's Davis Cup squad has been anchored by Rusedski and Tim Henman, the UK number one, in recent years.
But Felgate believes there are players coming through with the potential to step into Rusedski's trainers.
"You only have to go down to Queen's Club to see the environment in which our next level of players are working. The courts are buzzing," he told The Independent.
"Picking the Davis Cup team should be a headache and we're moving towards that."
Rusedski's hearing took place on 9 February, but he has since been forced to wait for the verdict.
Once the ATP's three-man panel release their judgement, the former US Open finalist will have 21 days to appeal to the Court of Arbitration for Sport (CAS).
