Pat Rafter has come out of retirement to team up with Lleyton Hewitt in the men's doubles at this year's Australian Open.
Rafter, Australia's Davis Cup captain, hasn't played on tour since he teamed with another Australian, Josh Eagle, in the 2004 Australian Open doubles.
The 41-year-old and Hewitt have been given a wildcard into the doubles draw, and will play America's Eric Butorac and South Africa's Raven Klaasen in the first round.
Australia's doubles options are limited, with Hewitt in recent years having to carry the full load of singles and doubles duties.
Asked if they'd consider rekindling their Davis Cup partnership if they went well this week, Hewitt said: ''I doubt it. We won't have anybody to sit on the side of the court. We can't do that''.
Rafter was equally coy when the Davis Cup theory was put to him.
''I hope not. There would have to be food poisoning, sicknesses. That would be my worst nightmare,'' he said.
Hewitt, who even gatecrashed Rafter's press conference to joke about the one-time world No.1's comeback, maintained playing doubles together at the Open with his long-time friend was ''just a bit of fun''.
''I actually asked him a little while ago,'' Hewitt said.
''He still hits a lot at the Davis Cup ties, works us out a bit. Yeah, it's just a bit of fun.
''It will be nice on my off days - hopefully I'm still in the singles - to go out and play dubs with Pat.
''He's hitting the ball well enough. He beat Ivanisevic and Henman and those guys over in the seniors tour.''
An ITF spokesman said Rafter was eligible to play at the Open because he never actually retired from the Tennis Anti-Doping Program.
If he had, the two-time US Open champion would have had to apply for a return and wait three months for an all-clear.
''I obviously looked up to Pat a hell of a lot growing up,'' Hewitt said.
''He really helped me out. It's great that he's Davis Cup captain for me now, as well. Most likely I'll finish my career with him as Davis Cup captain, which is fantastic for me as well.
''While we're still able to move around the court together, it's nice we can go out there and play in a grand slam.''
Rafter, who plays regular matches on the veteran's tour, retired from the singles tour at the end of 2002, after a career that saw him win two US Opens (1997 and 1998).
He won the Australian Open doubles title with Sweden's Jonas Bjorkman in 1999.
