Quadri Aruna lost 3-4 in his round of 64 match at the South Paris Arena to Eduard Ionescu of Romania.
Aruna’s hopes of repeating his Rio 2016 quarter-finals performance went up in smoke when the 20-year-old Ionescu made it a thrilling Olympic debut for himself.
He rallied back to win with an 8-11 9-11 6-11 11-8 12-10 11-9 13-11 scoreline, in spite of having played a match earlier in the day.
The Nigerian won the first three games —- 11-8 11-9 11-6 —- only for Ionesco to turn the match on its head by winning the next two games —- 11-8 12-10—- to take the match to seven games.
His opponent then won 11-9 13-11 to take the match and head to the round of 32.
Earlier in the day, Olajide Omotayo had lost 1-4 to Iranian Noshad Alamiyan.
The result meant both Nigerians are out of the men’s singles event of the competition.
