Are you ready for some football ... brain injuries as diagnosed by Will Smith in "Concussion"?

The A-lister plays real-life forensic pathologist and neuropathologist Dr. Bennet Omalu, who discovered chronic traumatic encephalopathy (CTE) in the brains of NFL players and fought for the truth to be known. Peter Landesman ("Parkland") directed "Concussion," which was produced by Ridley Scott, based on the 2009 GQ article "Game Brain."

Peter King just shared the movie's first trailer in his Sports Illustrated column: "Concussion" opens on Christmas Day, so maybe we can expect Will Smith's name to come up on Oscar lists, for his portrayal of the Nigeria-born doctor. The movie also stars Alec Baldwin, Luke Wilson, Gugu Mbatha-Raw, Arliss Howard, Paul Reiser, David Morse, and Albert Brooks.

Watch the trailer.
