Dr. Ann McKee, a concussion specialist, wants the hockey community to step up its game when it comes to posthumous brain donation.

McKee, the chief of neuropathology at VA Boston and director of Boston University's CTE Center, has been at the forefront of football concussion research for years -- but she has yet to see the hockey community donate brains posthumously at the same rate as football.

"We're not nearly as far in hockey [research] as we are in football because we just don't have the same numbers," McKee said in a phone interview with ESPN.com.

Released in late July, McKee's study showed 177 of 202 deceased football players' brains had chronic traumatic encephalopathy -- commonly referred to as CTE. This included 110 of 111 brains of NFL players.

According to a Boston University CTE Center research assistant, neuropathology has been completed on just 16 hockey players' brains, nine of which were found to have CTE. All six of the NHL players' brains in the study had CTE. In total, 19 brains from hockey players have been donated to the center.
