During the instances of Whereabouts Failures, Johnson, aged 28, was part of the USADA Registered Testing Pool (RTP), which comprises a specific set of elite athletes subject to Whereabouts obligations to facilitate out-of-competition testing. Over a span of 12 months, Johnson accumulated three Whereabouts Failures: the initial one on 29 October, 2022, the second on 13 June, 2023, and the third on 10 October, 2023.

The accumulation of three Whereabouts Failures within a 12-month period constitutes a breach of regulations under the USADA Protocol for Olympic and Paralympic Movement Testing, the United States Olympic and Paralympic Committee National Anti-Doping Policy, and the International Ski and Snowboard Federation Anti-Doping Rules, all of which adhere to the World Anti-Doping Code. 

Sanctions for Whereabouts rule infractions typically range from one to two years based on the athlete's level of culpability. In this instance, USADA determined that a 14-month suspension was appropriate due to Johnson's relatively low degree of fault, taking into account the circumstances of the case.

Johnson's 14-month period of ineligibility commenced on 10 October, 2023, which corresponds to the date of her third Whereabouts Failure. Furthermore, all competitive results achieved on and after the said date, have been annulled, leading to forfeiture of any medals, points, and prizes.

Born in Jackson, Wyoming, Johnson was raised in the nearby town of Victor, Idaho. She made her World Cup debut in December 2015. During her inaugural World Cup season in 2017, she secured the eighteenth position in the downhill standings. 

However, during the World Cup finals in March at Aspen, Johnson encountered a crash in the downhill race, resulting in a tibial plateau fracture to her left leg. Despite this setback, she swiftly recovered and went on to finish eleventh in the downhill standings during the 2018 season. 

Johnson also competed in the Winter Olympics that year, securing the seventh position in the downhill event and the fourteenth position in the super-G. In September 2018, while training in Chile, Johnson suffered a partial tear to her right anterior cruciate ligament (ACL), leading her to miss the entire 2019 season. 

Upon her return to snow, she encountered another setback when she tore her left posterior cruciate ligament (PCL) and medial collateral ligament (MCL) in her left knee during training in June 2019. Despite these challenges, Johnson made a comeback to the World Cup circuit in January 2020 with a 25th-place finish in the downhill event at Altenmarkt, followed by consecutive top-ten finishes at Bansko.

Her breakthrough moment came in December 2020 when she clinched her first World Cup podium at a downhill event in Val d'Isere, France. Although she qualified to represent the United States at the 2022 Winter Olympics, Johnson was unable to compete due to an injury.
