Speculation is running around that Lars Sullivan will be making his return to TV at Takeover or the pre-Takeover NXT TV tapings. Lars returned to working live events in mid-July after being out of action for a month with a broken jaw. Lars has not worked a set of TV tapings since May 9 and his last TV match came on June 16, the loss to then-NXT Champion Aleister Black at the "Takeover: Chicago II" event.
The very last tweet made by Lars was fairly recent.
