#3 Ladder Match with the Universal Championship Match Contract hanging above
Now this is an outside possibility and the chances of this happening are very few. Braun Strowman was supposed to challenge Brock Lesnar for the Universal Championship at the Royal Rumble pay-per-view but with his elbow injury the Monster seems to be out of the title picture now.
So, the WWE would want to crown a new #1 contender for the Universal Championship and having Balor and McIntyre clash off in a ladders match for the #1 contender-ship would be an apt decision. Finn Balor was the first ever Universal Champion and is yet to win the title back ever since returning while Drew McIntyre seems to the next big thing in the WWE and is the prime contender to win the title from Lesnar. Having Finn Balor win this match can satisfy the WWE Universe and the WWE could have McIntyre clash against Lesnar at the Grandest Stage later in 2019.
