Knyba (17-1, 11 KOs) also enters the fight looking to rebound. The 6-foot-7 heavyweight suffered the first defeat of his professional career in January, when Agit Kabayel stopped him in three rounds in their clash for the interim WBC heavyweight title. Before that setback, the Top Rank prospect had put together an unbeaten record while climbing the rankings.

The fight for Ruiz Jr. represents another opportunity to prove he can still compete with top heavyweights late in his career. A convincing win would help revive his standing after several years in which negotiations for major fights repeatedly failed to produce results.

The September 4 event has yet to be officially announced, but negotiations are reportedly at an advanced stage. If an agreement is reached, both heavyweights will enter the contest looking to put disappointing recent chapters behind them and move back into contention.
