Salwa Eid Naser faced disqualification at the Grand Slam Track Philadelphia after being adjudged to have committed a lane infringement violation. She was making her third appearance at Grand Slam Track after competing in Kingston and Miami where she secured second place in the long sprints.
The Bahraini sprinter competed in the 400m event alongside a star-studded lineup, including Marileidy Paulino, Nickisha Pryce, Isabella Whittaker, Alexis Holmes, Sharlene Mawdsley, Laviai Nielsen, and Jessika Gbai.
Eid Naser executed a remarkable start in the long sprint event and surpassed other athletes to follow Paulino in second place. However, after overcoming other athletes, she seemingly lost control of her direction.
During the last 100m of the race and the second curve, Eid Naser misjudged her step and barged into Pryce's lane. She started the race in the sixth lane but crossed the finish line from fifth.
Following the unfortunate incident, Eid Naser was disqualified from the race, due to a lane infringement rule violation, which requires the athletes to maintain their designated lane throughout the race in a few events (including 100m, 200m, 400m, and the 4x100m relay).
Salwa Eid Naser had earlier also faced disqualification at the 2024 Brussels Diamond League, where she committed the same violation in the women's 400m event.
