Great Britain's flag bearer Peter Norfolk will not be able to defend his wheelchair tennis singles title after losing 5-7 6-3 0-6 to Israel's Shraga Weinberg.
The 51-year-old started off poorly in the clash and struggled to hold his serve as he relinquished the opening set as Weinberg got a vital late break.
Despite a shaky start, Norfolk tried to fight back by regaining composure and snatching a break, which allowed him to push on and force through a deciding set.
The Brit, who won gold in Beijing and Athens, lost his first service game and failed to come back into the match as Weinberg cruised to a 6-0 lead and a place in the semi-finals.
Despite missing out on singles gold, Norfolk still has a chance to claim a medal in the doubles tournament alongside Andy Lapthorne.
