法贝尔(Urijah Faber)目前的职业战绩为33胜8负，他在过去的5场比赛中打出了3胜2负，去年5月举行的UFC Fight Night 66中被弗兰基-埃德加(Frankie Edgar)一致判定击败，这也是他职业生涯中输掉的第一场非冠军比赛。在去年12月举行的UFC194中，法贝尔(Urijah Faber)以一致判定击败了新星弗兰基-萨恩斯(Frankie Saenz)。

卢克(Luke Rockhold)目前的职业战绩为15胜2负，他在UFC首秀被维托-贝尔福特(Vitor Belfort)后旋踢KO后，一口气打出了5连胜，不仅全部终结对手，其中更是包含了迈克尔-比斯平(Michael Bisping)、町田龙太(Lyoto Machida)等顶级选手。卢克(Luke Rockhold)在去年12月的UFC194中第四回合TKO击败了韦德曼(Chris Weidman)，成为了第一位同时获得过Strikeforce和UFC中量级冠军的选手。

比斯平目前战绩为28胜7负，其中15次KO，4次降服获胜。他在今年2月于伦敦举行的UFC Fight Night 84中以一致判定击败了“蜘蛛”安德森-席尔瓦(Anderson Silva)，获得了职业生涯中最具分量的一场胜利。目前已经3连胜的他之前还先后判定击败了CB-道拉威(CB Dollaway)和泰利斯-莱特斯(Thales Leites)。

此外，当晚还有麦克思-荷洛威(Max Holloway) VS 里卡多-拉马斯(Ricardo Lamas)的羽量级高排位对决。荷洛威(Max Holloway)目前的职业战绩为15胜3负，其中6次KO/TKO，2次降服获胜。他目前已经打出了8连胜，上一场败绩还是在2013年时被康纳-麦格雷戈(Conor McGregor)一致判定击败。荷洛威(Max Holloway)在过去的两年里都各打了4场比赛并全部获胜，击败的对手中包括了卡布-斯旺森(Cub Swanson)、查尔斯-奥利维拉(Charles Oliveira)、杰里米-斯蒂芬斯(Jeremy Stephens)等，现UFC官方排名羽量级第4位。

拉马斯(Ricardo Lamas)目前的职业战绩为16胜4负，其中4次KO/TKO，4次降服获胜。他在签约UFC后的9场比赛中只输给过何塞-奥尔多(Jose Aldo)和查得-门德斯(Chad Mendes)这两位顶级实力的选手，其余的7战他不仅全部获胜，而且4次终结对手，其中包括了卡布-斯旺森(Cub Swanson)、哈卡瑞-迪亚斯(Hacran Dias)、丹尼斯-贝穆德斯(Dennis Bermudez)等。他的上一场比赛是在去年11月的“终极斗士 拉丁”决赛中判定击败了迪亚戈-桑切斯(Diego Sanchez)。

中量级方面，之前原定在4月的UFC On FOX 19中与町田龙太(Lyoto Machida)进行中量级二番战的丹-亨德森(Dan Henderson)由于对手的药物问题而退赛。亨德森(Dan Henderson)目前的职业战绩为31胜14负，他在此前的4场比赛中只赢下了1场，最近的一战是在去年11月与维托-贝尔福特(Vitor Belfort)的三番战中被首回合KO击败。这场比赛将是亨德森(Dan Henderson)与UFC合同上的最后一战，结束后他能否获得续约，以及是否会退役都是未知数。

隆巴德(Hector Lombard)目前职业战绩为34胜5负1平2无结果，其中19次KO/TKO，7次降服获胜。他在去年1月的UFC182中由于使用禁药而被禁赛了一年，击败乔什-伯克曼(Josh Burkman)的比赛也被改判无结果。今年解禁后，他在3月于澳大利亚举行的UFC Fight Night 85中对阵新星尼尔-马格尼(Neil Magny)，结果第三回合开始26秒后被TKO击败。赛后隆巴德(Hector Lombard)宣布升重回到自己最熟悉中量级发展。

While this was the first time the organization has held an event at the venue, it was the fifth time that UFC has hosted an event in Los Angeles County. Previous UFC events in the area took place at the Staples Center.

The event was expected to be headlined by a UFC Middleweight Championship rematch between champion Luke Rockhold and former champion Chris Weidman. They previously met at UFC 194, when Rockhold won Weidman's title via fourth-round TKO. However, Weidman pulled out on May 17 due to a large extrusion herniation on his neck.The first replacement choice was former Strikeforce Middleweight Champion Ronaldo Souza, who lost his title to Rockhold in 2011, but he injured his meniscus in a win at UFC 198 against former UFC Light Heavyweight Champion Vitor Belfort. Therefore, he was replaced by The Ultimate Fighter 3 winner Michael Bisping.The fight was also a rematch as the two met previously in November 2014 at UFC Fight Night: Rockhold vs. Bisping, with Rockhold winning via submission in the second round.

The co-main event featured a UFC Bantamweight Championship trilogy bout between the current two-time champion Dominick Cruz and former WEC Featherweight Champion Urijah Faber. The pairing first met at featherweight on WEC 26 in 2007, where Faber defeated Cruz via guillotine choke to defend his title. The rematch took place on UFC 132 in 2011, when Cruz defended his title for the first time via unanimous decision.

A lightweight bout between Evan Dunham and The Ultimate Fighter: Brazil 2 winner Leonardo Santos, originally scheduled for UFC 198, was moved to this event after a minor injury to Dunham delayed the matchup a few weeks. Subsequently, Santos pulled out on April 29 due to an undisclosed injury and was replaced by James Vick. In turn, Dunham pulled out of that pairing on May 5 for undisclosed reasons and was replaced by Beneil Dariush.

In January 2016, former UFC Lightweight and Welterweight Champion B.J. Penn announced his intention to return to active competition in the featherweight division after an 18-month "retirement" and was expected to compete at UFC 197. However, Penn's return was delayed after an investigation into criminal allegations made against him was launched. After the UFC concluded that no criminal or civil charges would be filed, the organization announced that he would face Dennis Siver at this event. In turn, Siver pulled out on May 10 due to an undisclosed injury. He was replaced by Cole Miller.Subsequently, Penn himself was removed from the card on May 23 after he was flagged for a potential anti-doping violation: the use of an IV in excess of 50 ml in a six-hour period during a March 25 out-of-competition sample collection. He was replaced by Alex Caceres.

A lightweight bout between John Makdessi and Mehdi Baghdad was originally scheduled for this event, but on April 28 it was announced that the bout was moved to UFC Fight Night: dos Anjos vs. Alvarez.

The event marked the first time fighters were allowed to weigh in for their bouts in the morning (starting 10 a.m.), rather than the traditional time of 4 p.m. used for public proceedings. They weighed in with a California State Athletic Commission (CSAC) official looking on so they would have less time to be dehydrated after their weight cuts and more time to rehydrate after making weight. They were back on hand to stand on the scale – ceremoniously, for the fans and media – and face off with their opponents. This is part of new measures for fighters' safety, with the CSAC creating new rules that will eventually be adapted to all the other athletic commissions.

During the main card broadcast, the UFC announced that UFC 8 and Ultimate Ultimate 96 tournaments winner Don Frye will be inducted to the UFC's Hall of Fame at the "International Fight Week" in July, one day after UFC 200.
