LONDON, England — Jamaica's 800m runner Kenia Sinclair is to cut her competitive season short due to lingering injuries that forced her to withdraw from yesterday's first round of the women's 800m at the Olympic Games, the Jamaica Observer has learned.

After gamely trying to make it to the starting line of what would be her second Olympic Games, Sinclair was forced to call it quits while in the warm up area, technical leader Don Quarrie told the Observer yesterday, adding that the athlete was "disappointed."

On Monday, Sinclair had told the Observer that despite what she calls a "whole bunch of injuries, one leading to the next", she would be making an effort to compete, putting aside the injuries that have plagued her all season.

Yesterday morning, however, Quarrie said she had to pull the plug while warming up as the injury was "still grabbing" and she did not think should be able to even finish the race.

Injuries have affected a number of athletes as sprint hurdler Latoya Greaves was also unable to perform due to an oblique injury she picked up in training and decathlete Maurice Smith, who has a problem with his sciatica, the nerve running from the middle of the back all the way to the toes.

Ludlow Watts, team manager had told the Observer that Greaves had decided she would not be able to compete as far back as Saturday after she pulled up lame while warming up with a recurrence of an injury she sustained in training on July 26.

Two 400m runners Jermaine Gonzales and Rushane McDonald were badly hampered by injuries in their first round heats as well, while sprinter Asafa Powell pulled up lame in the men's 100m final on Sunday after aggravating a long-time groin injury.

Gonzales and McDonald were, however, seen training with the 4x400m squad yesterday.

Sinclair, the national record holder with one minute, 57.88 seconds, has been bothered by injuries all season and has a season-best two minutes, 01.55 seconds this season, the time she ran to win the title at the JAAA/Supreme Ventures National Trials in June.

On Monday, Sinclair, who was sixth in the women's 800m final at the Beijing, Olympics, told the Observer she was dealing with a bulging disc in her back, as well as lumbar problems among others, but said while this was "unfortunate" she was still giving it a go.
