Warburton, 23, injured a nerve in his shoulder during Wales' RBS 6 Nations Grand Slam decider against France in March making him a doubt for the Red Dragons three-Test tour of Australia and the Barbarians clash in Cardiff on June 2.
But faith in the men around him leaves him confident that, if picked to start against the Wallabies on June 9 in Brisbane, any lack of match sharpness will not be exposed by last year's Tri-Nations champions.
"I may be a bit short of match fitness which might tell in the last ten minutes, but with 14 other super-fit guys on the field hopefully it won't be too much of an issue," said Warburton.
"Earlier this week I did a session with some upper body circuits, and I did some contact pad work and have had no issues so far. The physios and I are very happy.
"I am waiting for an appointment to see (specialist) Michael Fox in London but that is just a final check-up.
"The physios said they will judge it on how I feel functionally when I am training, so if I am happy with it and I can take part in contact with no pain then happy days.
"Before that (the injury) I had had a run of 14 or 15 Tests for Wales without picking up any injuries, that spell was always going to come to an end so maybe my body was telling me the games were taking their toll.
"We sat down with the physios and conditioners and they said this was a good chance to make sure my knee and shoulder problems go away and now I can fully take part in all sorts of training, so maybe it was a bit of a blessing.
