WEC 45: "Cerrone vs. Ratcliff" is officially set to go down as all 20 participants competing on tomorrow night's event made weight earlier today from the Key West Ballroom at the Palms Casino Resort in Las Vegas.

WEC 45 takes place tomorrow, on Dec. 19, at The Pearl at the Palms Casino Resort in Las Vegas, NV and the event's main card will be televised on the Versus network beginning at 10 p.m. EST.

The event will be headlined by a lightweight bout between contenders Donald Cerrone and Ed Ratcliff. Both men weighed in at 155-pounds. In the co-main event, former IFL star Chris Horodecki will make his much anticipated WEC debut against rising contender Anthony Njokuani in another featured lightweight bout.

Horodecki successfully weighed in at 155 lbs, while Njokuani had a bit of a hard time making weight, initially weighing in at 157-pounds, which is one pound over the 156-pound lightweight limit. He was given one hour to lose the additional pound and weighed-in at 156 pounds on his second attempt.

Other bouts featured on the main card include Joseph Benavidez vs. Rani Yahya in a bantamweight contest. In other bantamweight action, Scott Jorgensen and Takeya Mizugaki will meet in a fight that could potentially earn "Fight of the Night."

Besides Njokuani, Mizugaki is the only other fighter on the card to not make weight on his first attempt. He first weighed-in at 137 lbs, which is one pound over the 136-pound bantamweight limit. Mizugaki was then given a hour to shed the extra pound and did so by weighing in at 135 lbs on his second attempt.
