Boxing competition
Mike Tyson vs. Pinklon Thomas, billed as Hard Road to Glory, was a professional boxing match contested on May 30, 1987, for the WBA and WBC heavyweight championships.
Background.
This fight, along with the Tucker-Douglas fight that preceded it and served as the co-main event of the broadcast, were the two penultimate matches in HBO’s "Heavyweight World Series"; this was a tournament devised by the three major world sanctioning bodies, HBO, and promoter Don King to unify the heavyweight championships and crown an undisputed champion. 
To this point in the tournament, which began when Trevor Berbick defeated Thomas to win the WBC title in March of 1986, Tyson had already won two of the three available titles, knocking out Berbick in Berbick’s first title defense later in 1986 and then defeating James "Bonecrusher" Smith by unanimous decision earlier in 1987 to win the WBA title. 
Meanwhile, as the bout between Tyson and Thomas was signed, another was ordered to settle the IBF championship as reigning champion Michael Spinks, who had entered the tournament as champion and had already defeated Larry Holmes and Steffen Tangstad during its course, was to face challenger Tony Tucker, with the winner meeting either Tyson or Thomas in the final match to unify the titles. However, Spinks elected to pursue a more lucrative fight with former contender Gerry Cooney, and the IBF responded by stripping Spinks of their championship. Tucker and James Douglas, the top two contenders, were then paired to fight for the vacant IBF title and the bout was signed for the same night as Tyson vs. Thomas.

Tyson was the aggressor for nearly the entire fight, constantly getting the better of Thomas with his power punches. Tyson was nearly able to get the victory in the first round. With about 40 seconds left in the round, Tyson staggered Thomas with a left hook–right hook combination. With Thomas' back now against the ropes, Tyson delivered an 8-punch combination in an attempt to get the knockout victory, but Thomas was able withstand Tyson's assault and survived the round without being knocked down. Thomas was able to rebound and last another four full rounds with Tyson, using his left jab to keep Tyson off-stride while clinching Tyson whenever Tyson came close. The fight would come to an end with a minute remaining in round 6. 30 seconds into the second minute, Tyson was able to catch Thomas with a left hook that clearly hurt the challenger. Tyson would follow this with a relentless 15-punch combination that dropped Thomas to the canvas for the first time in his professional career.
