Jamaican sprint stars Shelly-Ann Fraser-Pryce and Shericka Jackson scratched from their signature events at the Paris Olympics.

Here’s what you need to know:

– Moments before the women’s semifinal at the Stade de France on Saturday evening, Shelly-Ann Fraser-Pryce's lane was unexpectedly empty. The Jamaican legend did not start the race.

– For hours, no explanation was given for her withdrawal. Later, on Instagram, she expressed her disappointment and thanked her fans for their support, but did not elaborate on the reason behind her decision.

Here’s what she wrote on Instagram:

“It is difficult for me to find the words to describe the depth of my disappointment. I know that my supporters share and shoulder this disappointment with me. I am truly Blessed to have had the steadfast support of my fans since my Olympic debut in 2008. The support of my fans, my country, and the larger community has rooted me in immense gratitude that has sustained me throughout my career. With every step and win, you all have been there for me. My Faith has always affirmed my trust in my journey. Thank you for continuing to be with me today and every day.”

Additional Details Sought

– Hours before the meet started, a video surfaced on social media that showed Fraser-Pryce was in a heated discussion with security officials not allowing her to enter the warmup track. Cameras later showed her warming up but several athletes in her section said she did not enter the call room.

“They changed the rule yesterday,” she says in the video. “How can they change the rule and then not say? So you’re asking all the athletes who for whatever reason don’t stay in the village, they can’t come through the gate. That’s crazy.”

– Fraser-Pryce was not alone in the issue. Sha'Carri Richardson was initially denied access. She was spotted in the video sitting on the curb by the gate.

– Richardson did elect to compete in her semifinal and finished behind Julien Alfred in 10.89 seconds. Alfred went on to win gold in the final. Richardson claimed her first Olympic medal with a silver.

– World Athletics later told The Telegraph that Fraser-Pryce’s withdrawal was purely due to injury. Jamaica’s team manager Ludlow Watts also said: “We only got the information that she is injured, but doctor Warren Blake is addressing the matter and we will speak further on the matter. This was a surprise and disappointment because the whole world would love to see Shelly in the Olympics. Apart from being a Jamaican, I am sure that people who love track and field would be very disappointed globally.”

– As of Sunday afternoon (5 p.m. local time), Fraser-Pryce has not shared any additional updates. Her status for the 4x100m relay remains unknown.

Another unexpected withdrawal

– Shericka Jackson withdrew from the 100 meters days before the start of the Games but was planning to race the 200m. She was listed as a DNS on the start list just moments before the 200m on Sunday morning.

– Before the Olympics, Jackson told reporters that a world record was not happening at the Olympics. She won last year's World Championships in Budapest in 21.41, which is just .07 shy of Florence Griffith Joyner's 36-year-old world record.
