Rumour: Sami Zayn to join the Shield?

Sami Zayn to join the Shield?

Over the past several weeks there has been speculation that WWE could possibly be adding a fourth member to The Shield group.
Recently one of NXT’s top wrestlers replied to an earlier tweet from Seth Rollins saying that he “believes in the Shield”. Rollins wrote the following message on Tuesday:
“Tearing down that wall. Brick by brick by brick. We don’t need no thought control. #BelieveInTheShield #raw”
NXT Star Sami Zayn,(AKA El Generico) then later responded with:
“@WWERollins I believe in the Shield.”
