Context: František Kasanič (born 2 March 1976) is a Slovak pro boxer. George Kelly Scott (born December 20, 1966 in Liberia), earlier George Cramne, is a retired Swedish professional boxer of Liberian descent.  He won the Swedish championship five years in a row, took a silver medal in the Olympic games in Seoul 1988.  He became a pro boxer and trained for the legendary Angelo Dundee and won the world champion belt for WBU.  He never lost his belt in the ring but because of disagreement with his manager and the title was taken from him. Facing Ali is a 2009 documentary directed by Pete McCormack about Muhammad Ali (born Cassius Marcellus Clay, Jr. in Louisville, Kentucky) as told from the perspectives of some of the notable opponents he faced during his career: George Chuvalo, Sir Henry Cooper, George Foreman, "Smokin'" Joe Frazier, Larry Holmes (a former sparring partner of Ali), Ron Lyle, Ken Norton, Earnie Shavers, Leon Spinks and Ernie Terrell. Ronald "Ron" Lyle (February 12, 1941 – November 26, 2011) was an American professional boxer who competed from 1971 to 1980, and in 1995.  He challenged once for the undisputed world heavyweight title, losing to Muhammad Ali in 1975.  Lyle was known for his punching power, crowd-pleasing fighting style, as well as courage and determination inside the ring.  He held notable wins over Buster Mathis, Oscar Bonavena, Jimmy Ellis, Earnie Shavers, Joe Bugner, and Scott LeDoux, but is best known for his slugfest against George Foreman in 1976, which won Fight of the Year honors by "The Ring" magazine. Facing Ali is a 2002 book authored by Stephen Brunt; it is about fifteen different fighters from around the world who battled with Muhammad Ali in boxing fights.  In each chapter of the book, one of the selected fighters recalls the experience of fighting with Ali.  The profiled fighters include Ali's famous opponents like George Foreman, Joe Frazier, and Ken Norton; and also the relatively obscure like the German butcher Jurgen Blin who "was back at work at the sausage factory" after having fought with Ali the previous day.  Other fighters profiled in the book include Tunney Hunsaker, Jean Pierre Coopman, Henry Cooper, Ron Lyle, Chuck Wepner, George Chuvalo and Larry Holmes.

In only his eighth professional fight, he won the undisputed heavyweight championship in 1978 after defeating Muhammad Ali via split decision, in what was considered one of the biggest upsets in boxing history.  Spinks was later stripped of the WBC title for facing Ali in an unapproved rematch seven months later, which he lost by unanimous decision. Kenny Bristol (born March 9, 1952) is a Guyanese professional light middle/middleweight boxer of the 1970s and '80s who won the Commonwealth light middleweight title, his professional fighting weight varied from 153+1/4 lb , i.e. light middleweight to 157+1/2 lb , i.e. middleweight.
