The Canberra teenager is the No.1 player in the country, fresh off a blistering quarter-final performance at the Australian Open and is the most exciting talent in world tennis.

But Masur knows the risks associated with young players coming back too early from injury, which is why he won't be putting any pressure on the 19-year-old in his comeback from a back complaint.

"I'm involved in a national academy in Sydney, so I know these things are things you don't want to mess around with," Masur said. "If you come back a bit early, you could end up with a fully-blown stress fracture.

"The rest of this year is important. It will be caution first. With my Davis Cup captain's hat on, would I want him there? Yes I do, but he has to be guided by his pain and how he feels and doctor's advice."

Masur and fellow former Australian greats Todd Woodbridge and John Fitzgerald were in Canberra on Thursday to support the Maxim Invitational fundraising event at the North Woden Tennis Club. They were also on hand at Thursday night's inaugural Tennis ACT gala dinner at the QT.

Kyrgios is back in Canberra to continue his rehabilitation after he pulled out of two tournaments to prevent problems with his L3 vertebra turning into a stress fracture.

Masur will catch up Kyrgios while he is in Canberra to find out how he is progressing before naming the Davis Cup squad on February 25.

Kyrgios has rocketed up the rankings in the past 12 months, leaping to No.35 in the world after progressing to the final eight at Melbourne Park. It was his second quarter-final appearance in a major after beating Rafael Nadal on the way to the last eight at Wimbledon last year.

Woodbridge said Kyrgios and his coaching team had made the right call to take a break to prevent any serious injury.

"The team around him have done a very good job in pulling the schedule back where necessary to maintain building a robust body that can last on tour in two or three years time and progress through a strong career," Woodbridge said.

"There's no point going too hard now and being out for six months because that will put him backwards. Nick is a very raw athlete in terms of body maturity, so he's got to take the time to continue to work on that. He's progressing terrifically well."

A fit and firing Kyrgios would strengthen Tennis ACT's bid to attract a Davis Cup tie as early as September this year. Tennis ACT is pushing for the redeveloped Lyneham Tennis Centre to be recognised on the national stage.

"I think it'd be awesome to play Davis Cup and Fed Cup here," Woodbridge said. "That's all part of the strategy to get facilities built here and around Australia, to give opportunity to put Fed Cup and Davis Cup in ties in areas where we can get a lot of support."
