After Dolph Ziggler won the United States Championship at Clash of Champions, He forfeited the title on the next episode of Smackdown Live.
With the title being vacant General Manager Danial Bryan started a tournament to see who will become the next United States Champion. WWE finally released a visual of the tournament and the 4 participants.
I expect the winner of this tournament to get a big push by the WWE in 2018.
