Oscar De La Hoya vs. Felix Sturm, billed as Collision Course, was a professional boxing match contested on June 5, 2004 for the WBO middleweight championship.

[1] Following a controversial loss to Shane Mosley that cost him the WBA and WBC light-middleweight titles in September 2003,[2] Oscar De La Hoya announced his intentions to move up to the middleweight division to challenge undefeated WBO champion Felix Sturm, followed by a unification bout with Undisputed Middleweight Champion Bernard Hopkins should he defeat Sturm.

[3] As a precursor to their planned fight, Hopkins and De La Hoya agreed to take part in a joint doubleheader pay-per-view event broadcast by HBO dubbed "Collision Course".

The first of the featured bouts saw Jose Luis Castillo win the vacant WBC and The Ring lightweight titles, after defeating Juan Lazcano by unanimous decision.

The decision was met with controversy as the Compubox punch stats showed that Sturm had a clear edge over De La Hoya in nearly every category.

De La Hoya was behind on two of the three scorecards before Hopkins ended the fight with a body shot that put him down for the count in the ninth round.
