KUALA LUMPUR: Aaron Chia-Soh Wooi Yik's return to competition ended in disappointment after they retired just six minutes into their opening-round match at the Kumamoto Masters Japan on Tuesday.

The third seeds were trailing India's Hariharan Amsakarunan-M.R. Arjun 11-6 in the opening game when they were forced to concede the Super 500 encounter.

The retirement raises fresh concerns over Wooi Yik's fitness after the 28-year-old suffered a right heel injury during last month's French Open.

The two-time Olympics bronze medallists had skipped the Hylo Open and Korea Open to allow Wooi Yik more time to recover before returning to action in Japan.
