Widely considered the greatest fighter of all time, Silva (33-6) hasn't fought since he defeated Nick Diaz via unanimous decision at UFC 183 on Jan. 31. After the fight, it was revealed that Silva had failed multiple drug tests (steroids) that had been administered by the Nevada State Athletic Commission. The NSAC banned Silva for one year and changed the result of his fight against Diaz to a no-contest.
Silva, 40, has maintained his innocence in regards to the failed tests. During a disciplinary hearing in August, the Brazilian legend blamed the failed tests on a contaminated sexual-performance-enhancing drug he was on.
The Jan. 31 bout was Silva's first since he suffered a broken leg during a UFC title fight against Chris Weidman in December 2013. Silva holds the UFC record for consecutive title defenses with 10. He won his first 16 bouts in the UFC before losing the title in a knockout loss to Weidman in July 2013.
Bisping (27-7) was originally scheduled to fight Gegard Mousasi on Feb. 27, but he now receives the matchup against Silva that he has long coveted. The British martial artist is tied for sixth all-time in UFC appearances with 24, but he has never fought for a UFC title.
Both Bisping and Silva signed with the UFC in 2006, but they have not crossed paths until now.
According to UFC officials, Mousasi (37-6) is expected to remain on the London card, which will air on the promotion's digital service UFC Fight Pass.
