Big Show knocks out Raw General Manager Brad Maddox.

Raw General Manager Brad Maddox suffered more than a loss of face after being hit with a KO Punch from Big Show on Friday’s SmackDown. WWE.com can confirm that Maddox has suffered a concussion after being knocked out by the fired giant, who had been allowed to attend the show and air his grievances towards The Authority and ended up blasting Maddox with his signature strike instead.

WWE physician Dr. Michael Sampson confirmed the diagnosis with WWE.com.

“[Brad Maddox] was knocked out, he did lose consciousness,” said Sampson. “[We] took him back to the training room and did some neurological tests on him, which were normal. He did have some slow papillary reaction, which goes along with a concussion, so at this point we have diagnosed him with a concussion.”

Dr. Sampson did not confirm whether the General Manager’s duties on Raw would be affected by the injury, but he did say that WWE medical staff planned to keep a close eye on Maddox.

“We’ll be checking in with him tomorrow for repeat and neuropsychological testing if appropriate, if he’s symptom-free,” said Sampson.
