In February 2016, Danielson retired from professional wrestling due to medical issues (including seizures) arising from multiple concussions and a brain lesion. That July, he became the SmackDown General Manager following the return of the brand extension. In March 2018, Bryan was formally cleared by doctors to return to in-ring competition and had his in-ring return at WrestleMania 34 on April 8 and regained the WWE Championship for the first time in four years later that November.
