Both Nick Kyrgios and Jack Sock anticipate being fit to keep competing this week despite being hampered by injuries on court.
Kyrgios called the trainer for his knee during his opener at Brisbane, and told press he had tweaked it during a practice session with Lleyton Hewitt a couple of days ago.
"I was playing some points with Lleyton and kind of felt my knee a bit," Kyrgios said following a three-set win. "I have been kind of nursing it but I didn't really know what it was."
"It had a bit of fluid in there leading up to the singles but it doesn't really hurt me when I move—when I am straightening my leg."
Kyrgios said the problem should not affect him during the rest of the week and at the Australian Open.
Sock had a fall and appeared to have hurt his hip during his singles match at Hopman Cup, retiring in the second set against Yuichi Sugita. He was, however, able to finish his match against Roger Federer on Thursday, but he lost that one in straight sets.
