Sami Zayn could be close to a return. WWE.com is advertising Zayn for the NXT UK tour dates in December, including NXT Takeover: London. Nothing has been confirmed as to his capacity in the appearances, of course; he could be making an appearance that doesn’t require in-ring action.
Zayn has been out since May with an injured shoulder that he suffered during his Raw debut against John Cena in a US Title match.
