The UFC is back in New York's Madison Square Garden this weekend -- and just like in 2016, it's bringing along three title fights.
In the UFC 217 main event, former welterweight champion Georges St-Pierre returns from a four-year hiatus to challenge middleweight champ Michael Bisping.
In the co-main event, budding superstar Cody Garbrandt seeks his first bantamweight title defense against a former teammate and champion in TJ Dillashaw.
Plus, strawweight titleholder Joanna Jedrzejczyk attempts to tie Ronda Rousey's historical female MMA mark of six consecutive title defenses, against two-time title challenger Rose Namajunas.
Here's everything you need to know about UFC 217.
Joanna Jedrzejczyk (14-0) vs. Rose Namajunas (6-3), Strawweight Championship
Odds: Jedrzejczyk -470; Namajunas +375
Joanna Jedrzejczyk's goal has never been to replace Ronda Rousey, but a look at recent history suggests she has.
November 2015: Jedrzejczyk defended her title in Australia, on the same night and in the same building as Rousey's infamous knockout loss to Holly Holm.
November 2016: Jedrzejczyk carried the torch for female MMA into New York, defending her title at UFC 205 in Manhattan. Rousey surfaced from isolation to square off against Amanda Nunes in a promotional event. She lost to Nunes the following month.
November 2017: Rousey is gone. Not officially retired, but nowhere near the UFC. Jedrzejczyk is preparing to tie her record of six title defenses. And she is the unapologetic face of women's MMA.
"I'm the champion for a reason and I will prove that on November 4th, baby," Jedrzejczyk said. "I'm making history one more time at the Garden."
Standing in Jedrzejczyk's path is the 25-year-old Namajunas, who is actually competing in her second strawweight title fight. Namajunas lost to Carla Esparza in the UFC's inaugural 115-pound championship fight in 2014.
It's been a fascinating psychological buildup to the fight, as Jedrzejczyk has attempted and intimidate Namajunas at every turn. The Polish champion is known for doing so.
Namajunas comes from a difficult background and has talked about her late, schizophrenic father. She's talked about fighting for those who have mental health issues.
Her coach, Trevor Wittman, says Namajunas's internal battles are far more important than Jedrzejczyk's mind games.
"When you come from an abusive lifestyle, you're the one who is always being controlled," Wittman said. "Her fears revolve around, 'Can she control the situation?' And that is the key to what makes Rose great. If she's able to stay in control of herself and control the situation, she's overcoming that obstacle in her life.
"Fighting for a title, against the best girl in the world, in front of millions, is not the true sense of who she is or why she fights."
Asked if her calm demeanor has possibly bothered Jedrzejczyk, Namajunas smiled.
"Oh, hell yeah. When the thing that always works don't work, that's when you start to panic," Namajunas said. "That's what I do with all my opponents. I shut down their strengths and take over from there."

Dana White's take
Jedrzejczyk is 14-0, about to tie Ronda Rousey's record. She'll have one more to break it. If you look at her history and career, she's one of the greatest fighters of all time. You look at significant strikes in a title fight, she's No. 1, No. 2, No. 3 and No. 4 on the list. That's crazy. Most leg kicks thrown in a fight, she's No. 1 and No. 2 on the list. She's unbelievable. Some people it takes a little bit longer than others to become a big star, but she's on the right track. She's on the right track.
ESPN's fight breakdown
Rose Namajunas is far more prepared to win a UFC championship now, than she was at age 21 in 2014. But is she prepared to beat Joanna Jedrzejczyk?
Over the course of a 25-minute fight? No. It's impossible to say she is. Namajunas is one of the best in the world, but she can't consistently beat Jedrzejczyk over five rounds. But can she surprise, and possibly finish her, at any given moment? That she can do.
That describes every fight, but it's meaningful here. Jedrzejczyk is the best. No one will top her on scorecards. If she loses, it will likely be a finish -- and Namajunas's career finishing rate is 83 percent, higher than any challenger Jedrzejczyk has fought.
The striking style Namajunas employs is fluid, and pretty to watch. She stays on the outside with footwork, jabs, front kicks. The range she maintains is blatantly long. Some previous opponents have been thrown off by it, coming up well short on offense, which opens counter opportunities for Namajunas.
The problem is: What happens when Namajunas loses that range? She was eaten alive in the clinch by Karolina Kowalkiewicz. Tecia Torres had success boxing Namajunas on the inside. Her commitment to that distance can also sabotage Namajunas's power. She tends to favor exit strategies over follow-up combinations -- although she does have a dangerous head kick.
Jedrzejczyk has lost a round to a long striker before in Valerie Letourneau, but again, over time, it's nearly impossible to beat her on the feet. She's effective at every distance, but with far more power than Namajunas -- and she's absolutely devastating in the clinch. If this matchup sees prolonged action in the clinch, it might be a very, very ugly night for the challenger.
And that's probably the No. 1 area of the fight to monitor. If Namajunas gets going on the outside, it forces her opponents to close. When they do, they walk into her scrambling and submission skills, which are really the best part of her game. That's where she took out the inexperienced Paige VanZant and the undersized Michelle Waterson.
If Namajunas pulls off the upset, here's what it likely looks like: Clean work on the outside, entice Jedrzejczyk to come forward and get off-balance, scramble, submission, tap. Easy, right?
Prediction: Jedrzejczyk via TKO, third round.
