Dark Match Jobber
I dont think he has to retire anybody but i can see him 'injuring' HHH to give HHH a 'legit' reason to have a rest. I would say Sheamus and HHH feud till just after Summerslam then Sheamus injures HHH and he get a few months off, just in time for a Royal Rumble return and heal turn, and Sheamus gets monster heat (quite similar to HHH, Orten storyline tho)
