This contrarian play has closed the gap in terms of odds between the two. When the official announcement was made, the odds stood at -1100 for the favorite Mayweather versus +700 for underdog McGregor. Now, the odds are a much closer -600 Mayweather vs. +400 McGregor.
Conor, UFC champion has never competed in a professional boxing match while Mayweather retired from the sport two years ago with a perfect 49-0 record.
