The two-time Cup Series champion missed the playoffs for the second straight year after failing to secure a win before the cutoff.Still, Busch has a chance to close out the year on a high note, aiming for his first victory since World Wide Technology Raceway in 2023. Four races remain on the schedule, with the South Point 400 at Las Vegas Motor Speedway set for Sunday at 5:30 p.m. ET.“I knew God was calling me to do more”: Kyle Busch's wife, Samantha, on becoming a certified fertility coachLast month, Samantha Busch announced that she had become a certified fertility coach, a step that aligns with her and Kyle Busch’s Bundle of Joy Fund initiative. She shared that earning the certification feels like a calling that God placed upon her.In an Instagram post, the 39-year-old IVF advocate and lifestyle blogger wrote:“This has been on my heart for so long. After walking through the heartbreak, the appointments, the waiting rooms, the tears, and the victories of infertility myself, I knew God was calling me to do more. I wanted to create a safe space where you can feel seen, heard, and supported, whether you need a sounding board to vent to, guidance navigating the different pathways to parenthood, or just someone who gets it.”“Now that I’m certified, I’m excited to have another outlet to support women through their journeys. I’m currently digging into the best ways I can use this to serve and encourage you all. So stay tuned for what’s to come, and tune into my stories to hear more about my journey,” she added.In addition to becoming a fertility coach, Samantha Busch also launched a podcast titled Certified Oversharer, where she discusses an unfiltered range of topics, including fertility and relationships. Kyle Busch once made a lighthearted guest appearance on one episode, joking that he channels his post-race frustrations toward his wife.
