Leon Bridges' "So Long," his touching contribution to Will Smith's upcoming football biopic Concussion, has arrived.

As we previously mentioned, the film is due out on Dec. 25, starring Smith as Dr. Bennet Omalu, a forensic pathologist who went up against the NFL after discovering a connection between head trauma from football injuries and degenerative brain disease.

With this latest cut, Bridges joins a hefty roster of artists who have contributed to films eligible for next year's Academy Awards, including Lady Gaga, Sam Smith, Miley Cyrus, Alicia Keys and Wiz Khalifa.
