UFC on ESPN: Ngannou vs. dos Santos

UFC on ESPN: Ngannou vs. dos Santos (also known as UFC on ESPN 3) was a mixed martial arts event produced by the Ultimate Fighting Championship that was held on June 29, 2019, at Target Center in Minneapolis, Minnesota, USA.

Background
The event was the promotion's third visit to Minneapolis and the first since UFC on FX: Browne vs. Bigfoot in October 2012.

A welterweight rematch between the former UFC Welterweight Champions Tyron Woodley and Robbie Lawler was expected to be the event headliner. Woodley won the title in their first encounter via first-round knockout in July 2016 at UFC 201. However, it was reported on May 16, 2019, that Woodley had suffered a hand injury and was pulled out of the fight. As a result, Lawler was removed from the card as well. Subsequently, a heavyweight bout between the former UFC Heavyweight Champion Junior dos Santos and former title challenger Francis Ngannou was scheduled as the event headliner instead. The pairing had been scheduled twice before, first at UFC 215 and then at UFC 239, but in both instances the fights were scrapped.

A light heavyweight bout between Roman Dolidze and Vinicius Moreira was scheduled to take place at the event. However, an unknown reason saw Dolidze pull out of the fight on May 7 and he was replaced by Eryk Anders.

A featherweight bout between Chas Skelly and Jordan Griffin was originally scheduled for this event. However, on June 13, Skelly pulled out of the fight citing injury. Griffin was then booked to face promotional newcomer Vince Murdock. On June 27, Murdock announced that he was not medically cleared to compete and the bout was removed from the card. On September 5, 2019, it was reported that Murdock had received a 20-month suspension by USADA, having tested positive for GW1516, better known as Cardarine and often sold on the black market as Endurobol, on a sample collected on July 6, 2019. Later in 2019, Murdock revealed that the reason behind withdrawing from the bout was initially high grade stenosis which was later diagnosed as Moyamoya disease.

A bantamweight bout between Sergio Pettis and Ricardo Ramos was scheduled to take place at this event but, on June 15, it was reported that Pettis had pulled out of the bout for undisclosed reasons and had been replaced by newcomer Journey Newson.

A light heavyweight bout between Justin Ledet and Dalcha Lungiambula was scheduled to take place at this event but, on June 24, it was announced that Ledet was removed from the card. He was replaced by promotional newcomer Dequan Townsend.
