Japan's Kei Nishikori is set to return to competition at the ATP Challenger Tour tournaments from late May through mid-June, according to his management.
The former world No. 4 last played on the ATP Tour in October 2021 before he underwent hip surgery in January last year and hurt his right ankle.
The 33-year-old is eyeing a return at three tournaments that will be hosted in Arkansas, Texas and Puerto Rico, his management said.
Nishikori, a winner of 12 ATP Tour singles titles, recently posted a clip of himself playing rallies on Instagram.
