Conor McGregor's return to the UFC cage might have to wait until 2024.
Yahoo Sports' Kevin Iole reported the former featherweight and lightweight champion didn't officially register with the U.S. Anti-Doping Agency.
"UFC fighters must be in USADA's testing pool for six months before they're able to compete again, meaning sometime in January 2024 is now the earliest McGregor could fight Michael Chandler, whom he's appeared with on the reality series, The Ultimate Fighter," Iole explained.
