Wade Barrett’s neck injury is said to be pretty serious, but WWE has not made an official statement on his injury.

He was off TV during TLC weekend, but he was backstage at the PPV and at Raw. He was on the road this week as well and he was used on Smackdown with League of Nations, but he hasn’t wrestled and he has done very little physically.

Barrett’s last match was on 12/8 during the Tribute to the Troops/Smackdown taping when he teamed up with Alberto Del Rio, Rusev and Sheamus against Dean Ambrose, Roman Reigns and The Usos. He also wrestled in a 16-man tag team match on that show.

WWE just doesn't want to admit another wrestler is injured

After the CM Punk situation they've been quite "reserved" when it comes to wrestl---- erm SUPERSTARS being injured or even wrestling through Injuries.
Which makes me wonder if they're actually fearing some kind of retaliation or whatnot from someone else...

Just like Daniel Bryan is still out on the shelf even though doctors said he's ok.
