The 32-year-old Dubliner has been out of action with club and country since January due to a thigh problem, but has been spending time at a specialist clinic in Qatar and his club say Andrews is close to a return.
Bolton's head of sports development Mark Leather said: "I've been in regular contact with Keith and getting regular updates from over there, so I've got a good idea where he is in terms of rehabilitation.
"He has gone over there with the blessing of the club and, to be fair, there have been a lot of changes here over the summer so we were all in and out.
"It's probably best for him that he goes somewhere like that and focuses fully on the task at hand.
"I'd imagine it was a great source of frustration to him that he missed such a large chunk of last season so he will be looking to push on soon and will be ready to go."
LIONS KEEN TO RETAIN FORDE
NEW MILLWALL boss Steve Lomas is determined to keep Ireland keeper David Forde at the club.
Forde has a year left on his contract with the Lions but the Galway native has been linked with a move to the Premier League, though Lomas is hopeful that Forde will stay loyal to the Lions
"We don't want David to go. Fordey loves it at Millwall and his family are settled," said Lomas
"I know him and he is the type of player I want.
"I certainly won't be looking to get rid of Forde or Liam Trotter. They are in their last year but that happens at every club."
REID INKS NEW BAGGIES DEAL
FORMER Ireland man Steven Reid is staying on at The Hawthorns after he agreed a new one-year deal with West Brom.
The 32-year-old had feared that his time with the Baggies was up but after talks with boss Steve Clark, Reid will remain on at the club.
"I am absolutely delighted to be staying, I never wanted to leave and I am happy we have reached an agreement," Reid said.
"I am looking forward to reporting for pre-season and hope we can build on last year's outstanding achievement in finishing eighth in the Premier League."
