Muhammad Ali vs. Jerry Quarry II, billed as Double Jeopardy, was a professional boxing match contested on June 27, 1972, for the NABF heavyweight championship.[1]
Ali called Quarry “the last of the white hopes” and described himself and Bob Foster as the soul brothers. Foster was facing Quarry's brother Mike as the first half of a double header.[2]
Ali was rated a 5‐1 favourite going into the bout.[3]
Quarry did better than in their first fight but once again struggled to close the distance with Ali, who once again dominated most of the fight from the outside. Quarry was hurt going into the seventh round, and after landing several unanswered shots, Ali signaled to the referee to stop the fight, which he did shortly afterwards.[4] [5] [6] [7] [8] [9] [10] [11]
Speaking after Foster's successful defence, his promoter Lou Viscusi suggesting he might move up to face Ali saying “I'd like to try that left for size on Ali”.
