Everyone comes to a crossroads in their life and I've come to mine. I look forward to telling you all about it tonight on #Raw.— Daniel Bryan (@WWEDanielBryan) December 29, 2014
For what it's worth, during media interviews in November, Bryan said that he still wasn't sure when he would return, but he hoped that it was in January so that he can be back for WrestleMania. During his interview with Michael Cole last month, Bryan said that while there was no timetable for his return, things were going better after he regained the strength in his arm.
