Sam Warburton is hopeful he will have recovered from the hamstring injury that ended his British and Irish Lions tour in time to lead Wales in their autumn internationals.
"The initial diagnosis was 12-16 weeks, I have been in doing rehab and we are on course for that," he told Sky Sports News.
"There have been no hiccups as yet, 16 weeks is the target, and all is going good so far."
The 24-year-old accepts that it may be difficult for him to find his way back into the Blues' line-up when he returns but wants to be involved in their Heineken Cup campaign, with Wales then facing South Africa at the Millennium Stadium at the start of November.
"If I could get back sometime in October, that would be good," he said.
"It will be difficult with the Blues to walk straight back into the side, obviously you have to work your way in, but Heineken Cup rugby is great to be involved in.
"If I can get back for that, that would be awesome."
