#3. Lio Rush costs Bobby Lashley the Championship
This is WWE, which means that Lio Rush hasn't been added to this match as an oversight, he is there for a purpose. Either Lio Rush is going to help Lashley retain the title and this could then cause a few issues when he asks The Almighty for a title shot in the future, or he will be the reason that Lashley loses it.
There are a number of combustible elements in this match, it's unknown as to whether or not Rush and Lashley will have to tag in and out of the match, which means that this could be a match that's over in minutes if both men are allowed in the ring at the same time.
Either way, there is a reason why Rush has been added instead of him lurking at ringside, so prepare for a storyline swerve of some kind.
