recovering from shoulder surgery
Isnt that when Sami got hurt? Aggressively swinging his arms during his US challenge entrance vs Cena
A good way to build it up would be for Cena to come out and say his "Lost my Smile" speech talking bout how he will be gone for awhile but he has one last "US title challenge" for anyone in the back.
We all wait anxiously for the entrance when Sami's theme hits (preferably in a smark town)
Sami comes out, has a 20 min classic with Cena to main event Raw. Sami gets the win to a huge pop and becomes the New US Champ
Cena does his usual stick of handshaking the fellow babyface and making gestures like Sami is the future of WWE
If done right, it should feel like when Bayley defeated Sasha for the NXT Divas title.
Puts Sami back on the map and creates a new Daniel Bryan esque upper midcarder
