There's no timetable on Edge's return as of now but a torn triceps usually requires around 8 months or so of recovery time and surgery.
The injury, like the finish to the match, was kept quiet through WWE until it was leaked today. The match itself went for around 35 minutes, but there's no word on if it was edited down.
