It did not take long for Rey Mysterio to get on the injured list again. Almost one month after making his return during a July episode of RAW, Rey Mysterio is on the sidelines yet again, this time however it’s due to a concussion.

The former World Heavyweight champion suffered the injury during his SummerSlam match against The Miz for the Intercontinental title and doctors have not cleared him to wrestle.

WWE pulled him out of upcoming shows until he gets the green light again. The company takes concussion injuries very serious and would not give permission to anyone to wrestle unless a doctor signs off.
