Andrews was concussion by GWS forward Jeremy Cameron several weeks back and suffered a small bleed on his brain that has kept him from playing.
Cameron was suspended for five weeks for the horrific incident.
Lions coach Chris Fagan confirmed by Friday morning that his vice-captain was nearing a return.
“He was given the all-clear this morning, so he can now start doing some contact work and he’ll be available for selection next week,” Fagan told the media.
“He was a bit sick and sorry the first week or two, but he’s made steady improvements since that point in time.
“You can see in his mood and his level of optimism and energy he’s back to his normal self.”
Josh Walker has filled in for Andrews at full-back in the past three weeks – all Brisbane victories – and done an exceptional job.
Fagan has explained how Andrews’ recovery will make for a pleasant selection headache for next week.
“It’ll be an interesting selection conundrum,” he said.
“I’m trusting Josh is going to play well again tomorrow (against Adelaide) and look forward to him playing a good strong game again.”
