Welcome to F4WOnline.com’s live coverage of UFC On FOX 23: Shevchenko vs. Pena, emanating from the Pepsi Center in Denver, Colorado.

The event is headlined by a five-round bout in the women’s bantamweight division, which could be a title eliminator bout, as first-ranked Valentina Shevchenko takes on second-ranked Julianna Pena. Shevchenko comes into the fight after winning a convincing decision over former champion Holly Holm in July. Shevchenko’s only UFC loss came to current champion Amanda Nunes, a bout in which she was winning late. Pena is undefeated in the UFC, having won four straight, and is coming off a win over former title challenger Cat Zingano.

The co-main event is a welterweight bout that has fireworks written all over it as Donald “Cowboy” Cerrone will square off against Jorge Masvidal. Cerrone has been on fire since moving up to the welterweight division as he has won four straight fights. Masvidal has been calling out Cerrone for a long time, and now he looks to add to his two-fight win streak by derailing Cerrone’s quest for a title shot.

Also on the main card is a heavyweight slugfest as former UFC Heavyweight Champion Andrei Arlovski looks to end a three-fight losing skid when he takes on rising heavyweight prospect Francis Ngannou, winner of eight straight fights.

Follow along with our live coverage of the event beginning at 4 p.m. eastern time with preliminary action all the way through the main card.

> Alexandre Pantoja (16-2, 0-0 UFC) vs. Eric Shelton (10-2, 0-0 UFC)
Flyweights

They traded early in the round with Pantoja getting the better of it with body kicks. Pantoja was able to take the fight to the mat and worked for the choke from the back before Shelton was able to spin free and get on top. They got to the feet and Pantoja landed a big kick but Shelton got a takedown close to the end of the round. A close first round but I score it 10-9 for Pantoja.

Pantoja was getting the better of the striking but Shelton was always able to reverse into takedowns. Pantoja went for a guillotine at one point but it didn’t come close to submitting Shelton. Shelton was able to land a flying knee before Pantoja score a takedown and took over the end of the round as he threatened with submissions from the back. They were pretty even on the striking this round but Pantoja’s ground control scored this round 10-9 for him, and I have Pantoja up 20-18 heading into the final round.

The pace slowed down in the third round considerably. That might be a common theme with the Denver altitude tonight. They stood on the feet and were just trading single punches. Neither man was doing much as the cardio was slowing them down. Pantoja was getting the better of the striking though Shelton stood toe-to-toe with him. This was Pantoja’s round 10-9 as he was the more effective striker. I have the fight 30-27 for Pantoja. This was a very good fight despite the slower-paced third round. Big mix of scores all over the place in this fight, and Pantoja took the fight on two of the three scorecards to get a split decision. It was definitely a close fight and one that could have gone either way.

Bantamweights

There were a lot of feints from Sterling as he was dodging punches from Assuncao. Sterling was keeping Assuncao at a distance with his long reach but Assuncao was able to land some punches. This was a close round as neither did a ton to win the round, but Sterling landing a lot of kicks may have gotten him the round. I have it 10-9 for Sterling.

Strange moment early in the second with a low blow from Assuncao that wasn’t called, but he didn’t jump on a hurt Sterling. Fans were booing the action in the round as not much was happening. Sterling wasn’t throwing any punches in the round and Assuncao was far more active. They went back to trading kicks and the fans were growing restless with the action in this round. They traded leg kicks late. I have round two 10-9 for Assuncao, and it tied up at 19-19.

They were trading and the pace was picking up. Sterling was landing more and keeping Assuncao at good range. The fans were still booing because while the activity picked up a little, it wasn’t all that exciting. Sterling started landing more late and threatened with takedowns in the round. Assuncao was missing more. This is a close fight overall. I have round three 10-9 for Sterling, and Sterling winning 29-28 overall, but this one will be interesting on the scorecards. Assuncao took the fight on two scorecards, which seemed like a good call as it was real close.

Official Result- Raphael Assuncao def. Aljamain Sterling by split decision (28-29, 29-28, 29-28)

> Nate Marquardt (35-16-2, 13-9 UFC) vs. Sam Alvey (29-8 1 NC, 6-3 UFC)
Middleweights

They had a grueling clinch battle against the fence. Both were switching positions but neither was able to get a distinct advantage. Not a whole lot of action went on and then when the ten-second block sounded, Alvey landed a big knee and came on with a late flurry that likely got him the round. It was really a nothing round for the first 98 percent of it. I have it 10-9 for Alvey.

Marquardt came on with a flurry as Alvey was clearing looking to set up a counter punch, but it was costing him early in this round. Alvey knocked Marquardt down at one point but did nothing to capitalize on it. Marquardt was bleeding from his cheek. Neither man was doing much and the crowd began booing.

Neither man did a lot in the last minute before Marquardt landed a combo in the closing seconds. I have round three 10-9 for Marquardt. I have the fight 29-28 Alvey overall. It will come down to how the first round was scored in my eyes. All three judges had the fight for Alvey. Alvey called for a fight against Jack Marshman in his post-fight interview.
