As seen on this week's episode of Monday Night Raw, Dean Ambrose suffered an elbow injury, and Samoa Joe and The Bar targeted it during a backstage attack following their six-man tag team match.
The elbow injury is legitimate, and Dave Meltzer of the Wrestling Observer Newsletter (subscription required) reported that Ambrose may have injured it back at the TLC pay-per-view show two months ago. Meltzer said that though the elbow didn't break, it did start swelling after hitting a table during the match.
It was later reported that Ambrose tore a triceps tendon, and he later underwent surgery to repair it. There has been no timetable given on when he will return, but we should expect Ambrose to miss at least multiple weeks, possibly months.
The injury leaves his fellow Shield members in the dark. Seth Rollins and Ambrose had been feuding with The Bar for the Raw Tag Team Championships, while Roman Reigns has defended his Intercontinental title against multiple superstars.
Ambrose is also in jeopardy of missing the Royal Rumble pay-per-view show, which is now a month away. He would have been one of the favorites to win it all, so we'll have to see how the creative team goes about it - if The Lunatic isn't able to compete by then.
Seth Rollins missed half a year after tearing his ACL and MCL during a house show two years ago, while Reigns recently returned after missing a month due to the mumps virus. For Ambrose, this is the first serious injury of his WWE career so far.
If Ambrose misses significant time, then the creative team will have to quickly find ways to adapt without him. This will impact the upcoming storylines for Reigns and Rollins, and could affect the Royal Rumble outcome. Hopefully, Ambrose only misses minimal time and can return before the road to WrestleMania begins.
