7 Surprises that can happen on RAW

6: Dean Ambrose returns

Dean Ambrose went out with a triceps injury late last year, effectively ending the Shield reunion in its tracks. Ambrose's injury was said to be worse than previously thought earlier this year but it looks like he could finally be ready to return.

With the Superstar Shake-Up being one of the biggest episodes of RAW in the year, there's a good chance that Ambrose will make his return if he is fit.
