The Lions captain injured his hamstring during the second Test defeat by Australia in Melbourne,
Warburton missed the Lions' record 41-16 win over the Wallabies in Sydney.
"The initial diagnosis was 12-16 weeks, I have been in doing rehab and we are on course for that," said the Cardiff Blues flanker.
"There have been no hiccups as yet, 16 weeks is the target, and all is going good so far."

Cardiff Blues kick off their Heineken Cup Pool 2 campaign when they travel to face English outfit Exeter Chiefs at Sandy Park on Sunday, 13 October.
"If I could get back sometime in October, that would be good," said Warburton.
"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."
