Dennis Andries vs. Thomas Hearns was a professional boxing match contested on March 7, 1987, for the WBC light heavyweight title.

[5] Hearns would put forth one of his most dominating efforts as he scored six knockdowns over the overmatched Andries.

As the WBC does not use the automatic knockout (three knockdowns in one round) rule that is enforced in WBA championship fights and in many state authorities, Andries was able to continue the fight though Hearns would take a commanding lead on the scorecards with a rare 10–5 round.

[8] Andries would rebound from his loss to Hearns and would reclaim the WBC light heavyweight title after defeating Tony Willis 2 years later in 1989.

After losing the title to Jeff Harding in his first defense, Andries would become capture his third light heavyweight title after knocking out Harding in their rematch, joining only Marvin Johnson at the time as the only three–time world champion in the light heavyweight division.
