The 35-year-old won her 23rd Grand Slam singles title at the Australian Open in January — a little less than 12 weeks ago — and has not competed since, citing a knee injury when withdrawing from tournaments at Indian Wells, California, and Key Biscayne, Florida.

She announced in late December that she was engaged to Reddit co-founder Alexis Ohanian.
