Cris 'Cyborg' Justino, Lina Lansberg to headline UFC Fight Night

Cris "Cyborg" Justino will make her second UFC appearance against Lina Lansberg on Sept. 24 in Brasilia, Brazil.

UFC officials confirmed to ESPN.com on Thursday that Justino (16-1) will headline a televised UFC Fight Night event. ESPN.com ranks Justino the No. 1 pound-for-pound fighter in the world.

The bout will take place at a 140-pound catchweight. Justino is the 145-pound champion for all-female promotion Invicta, but the UFC does not currently promote that weight class. Justino's UFC debut, a first-round TKO victory over Leslie Smith in May, also took place at 140 pounds.

Also added to the card is a heavyweight bout between Roy Nelson (21-13) and Antonio Silva (19-9-1). Both veteran heavyweights are coming off losses in their last respective contests.

Lansberg (6-1) is a 34-year-old Swedish featherweight. She is on a six-fight win streak, which includes four wins by knockout. She last fought on March 12 in Denmark.

Fighting out of Southern California, Justino is a former Strikeforce featherweight champion. A mega-fight between Justino and former UFC bantamweight champion Ronda Rousey teased fight fans for years, but never came to fruition -- mostly due to a difference in weight. Justino has stated numerous times it would be nearly impossible for her to drop to 135. Rousey and the UFC were never willing to agree to a catchweight.

In recent months, Justino has called for a catchweight fight against Rousey to take place at UFC 205 on Nov. 12 in Madison Square Garden. Rousey, who has not fought since she lost to Holly Holm in November, has not responded to Justino's challenge.

Justino, 31, has recorded 14 knockouts in her career.
