The following is from WWE.com:
“We’ve pulled him out of all activity,” said Amann. “His ImPACT scores are normal, but he’s still having some symptoms of fogginess and cloudiness.”
He continued, “We are waiting for symptoms to get better until we perform an in-ring exertional challenge later this week at the Performance Center in Orlando. At that point, if he’s able to get in the ring and exert himself, and work without symptoms, we’ll go ahead and clear him [to compete].”
