WWE Clash of Champions 2019: 3 Interferences that could take place at the PPV

#1 Harper returns to help Rowan defeat Roman Reigns

Harper is medically cleared and could return very soon

In a shocking turn of events, Rowan was revealed as the mystery attacker of Roman Reigns as he went on to decimate both The Big Dog and Daniel Bryan, this week on SmackDown Live.

Thus, what was expected to be an epic Roman Reigns vs Daniel Bryan matchup turned into Roman vs Rowan bout at Clash of Champions. Nonetheless, what may look like a damp squib at this point in time may very well turn into something huge on September 15.

Yes, in case you did not know, Rowan's former tag team partner and one half of the Bludgeon Brothers, Harper has been medically cleared for a while now and could return to WWE very soon.

Furthermore, one should not forget that after destroying Roman Reigns, Rowan went on to maul Daniel Bryan as well. Thus, WWE could have Harper feature on September 15 to help Rowan get a major win over The Big Dog. This would then lay down the breadcrumbs for an epic Roman Reigns and Daniel Bryan vs Harper and Rowan tag team matchup for the future.
