Michael Collins, a clinical psychologist who heads the UPMC Sports Concussion Program, continues to oversee Crosby but has been joined by Dr. Joseph Maroon, the Steelers’ neurosurgeon and WWE consultant who helped develop the ImPACT test widely used by professional and college teams to determine concussion severity.
Maroon recently was part of a medical team that oversaw the Flyers’ Chris Pronger, who is out for the season with a concussion.
Dr. Chip Burke, the Penguins’ team physician, is the only person permitted to clear Crosby for game action.
Shero declined to comment when asked if Crosby has visited Ted Carrick, a chiropractor based in Florida. Carrick worked with Crosby in August.
“I can tell you that Sidney isn’t going to come back until he is 100 percent healthy,” Shero said. “If he’s having symptoms of any kind, we’re not going to let him back into the lineup. It’s that simple.”
