Nick Kyrgios will be fit for next week's Australian Open despite pulling out of his Kooyong Classic match against David Goffin with a foot injury on Wednesday.
The outspoken Australian had called for a medical time out at 3-2 in the first set of the exhibition event before winning it in a tiebreaker against his Belgian opponent and called for the trainer again at 1-1 in the second.
The world No. 30 carried on briefly but opted to quit at the next changeover while trailing 3-2.
"Hate withdrawing, so sorry to everyone @KooyongClassic," Kyrgios posted on Twitter.
"I just have to make sure I'm right for next week & I will be."
Kooyang Classic tournament physiotherapist Rob Hanna said the Australian had a soft tissue inflammation and that he would be fine with rest and ice packs.
"It was there a little bit this morning when he hit up before the match," Hanna was quoted as saying by Australian Associated Press.
"He got to 2-3 in the first set and said he noticed it a bit more and that's why he called me out."
Kyrgios, 20, is in good form, having helped Australia win the mixed-team Hopman Cup event in Perth last week, where he beat British world No. 2 Andy Murray.
