The Belarusian announced on Thursday that she would not play in the Qatar Total Open, an event she has won in each of the past two years.

Azarenka said: "I am sorry I can't make it to Doha for the Qatar Total Open, but unfortunately I haven't been able to recover on time from my ongoing foot injury.

"I am thankful to all my fans in Doha and I look forward to coming back next year."

Serena Williams is due to head the field at the tournament which gets under way on Monday.
