The Ultimate Fighting Championship Lightweight no. 1 contender will be decided Jan. 25 at the United Center, 1901 W. Madison St., as fighters Ben Henderson (#1) takes on Josh Thomson (#4).

Henderson comes into the bout with a 19–3 record with two of those losses going to current UFC Lightweight Champion Anthony Pettis. Henderson is coming off of his most recent loss, as Pettis ended the fight late in the first round with an arm-bar submission.

Thomson has taken a different road to this matchup. After a long stint in Strikeforce, Thomson made the jump to UFC and debuted against veteran, Nate Diaz. Thomson knocked out Diaz in the second round.

Friday evening the two weighed-in and made the 155-pound cutoff for the fight, as well as the rest of the fighters for their respective weight classes.

The original bout scheduled for December was thrown out due to a knee injury sustained by current champ, Pettis. This fight will shape the rest of the division, with fighter Gilbert Melendez waiting in the wings.

If Thomson wins, UFC President Dana White has guaranteed that “The Punk”—Thomson’s well-known nickname—will be the next fight once Pettis returns to the ring.

Tomorrow, one of the main events will be Stipe Miocic taking on Gabriel Gonzaga in a heavyweight bout. Gonzaga weighed in at a significant 13 pounds heavier than Miocic, though still within the heavyweight range.
