Ivanovic, runner-up to Maria Sharapova at last month's Australian Open, slipped on the baseline when leading Govortsova 6-3, 5-1, and struggled to finish the second-round match.

"It's still pretty painful and hard for me to step on. I'm very disappointed the way I had to end this tournament," Ivanovic told reporters.

"I was icing my foot all night. I had to wake up every one hour so I didn't get much sleep but hopefully the team around me can help me to recover as fast as I can."

Ivanovic said she had not suffered a major tear.

"It's a strain, an overstretch of the ligaments," she said. "There's not any major tear, which is definitely good, but there are a few micro-tears there.

"I still get a lot of pain and have to keep icing my foot and keep it compressed and elevated to try to keep the inflammation down."

Ivanovic is hopeful of competing at the Dubai Tennis Championships next week. Because of a first-round bye, she would not have to play until Wednesday.

"That's definitely my goal but it's too early to say yet," she said. "If I can be on court by Monday or Tuesday I'd like to play but it's hard to say at the moment."

Her scheduled opponent in Qatar, 16th seed Agnieszka Radwanska of Poland, received a walkover into the quarterfinals where she meets sixth-seeded American Venus Williams or Slovak Dominika Cibulkova.
