Victoria Azarenka has admitted she's disappointed to miss the Fed Cup final for Belarus but is already looking forward to 2018.
The former world number one is in the US as she works through some family issues as she attempts to win a custody battle over her baby son.
She misses this weekend's Fed Cup final against the US and the 28-year-old, who has not been on court competitively since July, says it's a big sacrifice to make although she had no choice.
"As you probably saw this week, I will not be able to be a part of the Fed Cup final this year," she said in a statement released through her Twitter account.
"It is heart-breaking for me to not have a chance to play and help Belarus in the final, but unfortunately, my current situation is keeping me in California.
"Even though I will not be in Minsk for the final, my heart is always with my country and my team and I will cheer for them from afar."
Azarenka insists she will be back playing next year and thanked fans for their ongoing support.
She added: "While it has been a tough year for me, I am already looking forward to 2018 and playing before my fans very soon. As always, I want to send you my gratitude for the support you give me every single day with your notes and messages.
"I will be back stronger and better than ever!"
