Miguel Marriaga continued his comeback Saturday night from his technical-knockout loss to Vasiliy Lomachenko.

The Colombian contender stopped journeyman Jose Estrella with a body shot in the fourth round of their scheduled 10-round featherweight fight on the Miguel Berchelt-Miguel Roman undercard at Don Haskins Center in El Paso, Texas. Marriaga’s hard left to Estrella’s body sent the Mexican veteran to the canvas and left him writhing in pain.

Estrella couldn’t get up before referee Rocky Burke counted to 10. The time of the stoppage was 2:43 of the fourth round.

The 32-year-old Marriaga (27-3, 23 KOs) knocked down Estrella (20-15-1, 14 KOs) once apiece in the third and fourth rounds. A quick left hook to Estrella’s jaw knocked him down the first time, with 1:08 to go in the third round.

He answered Burke’s count and made it to the end of the round.

Estrella started strong by using his jab in the first round. Marriaga slowed him down by landing a hard right to the body during the second round, when Marriaga applied pressure and didn’t allow Estrella to get off punches.

Marriaga has knocked out both opponents since his TKO defeat to Lomachenko (11-1, 9 KOs) in August 2017. He moved back down to 126 pounds after losing that WBO 130-pound championship match to Ukraine’s Lomachenko in Los Angeles.

Earlier Saturday night, junior lightweight prospect Robson Conceicao dominated Canada’s Joey Laviolette in a completely one-sided eight-rounder Conceicao won by unanimous decision.

Conceicao, a 2016 Olympic gold medalist from Brazil, won by the same margin on each of the three scorecards (80-72). Conceicao, 30, upped his record to 10-0, yet failed to record a knockout for the fourth time in his past five fights.

The bigger, faster Conceicao basically took target practice on Laviolette throughout the first half of their fight. He landed an assortment of power shots to his opponent’s head and body, but never appeared to hurt Laviolette (9-2, 5 KOs), who hasn’t been knocked out as a pro.

By the sixth round, Conceicao appeared content to land occasional shots and win a one-sided decision.

Lightweight: Saul Rodriguez (22-0-1, 16 KOs), TKO 2, 1:57, Claudio Tapia (28-19-4, 13 KOs).

Rodriguez said: "I was anxious and excited to get back in there after such a long time out of the ring. It was a long time coming, but I did what I had to do and got the job done."

Welterweight: Nicklaus Flaz (6-1, 4 KOs), unanimous decision, 8 rounds, Sagadat Rakhmankulov (3-1, 1 KO). Scores: 78-73, 77-73, 76-75.

Super Middleweight: Janibek Alimkhanuly (4-0, 1 KO), split decision, 8 rounds, Vaughn Alexander (12-2, 8 KOs). Scores: 79-73 Alimkhanuly, 77-75 Alexander, 78-74 Alimkhanuly.

Middleweight: Zach Prieto (4-0, 3 KOs), KO 1, :45, Michael Andrews (1-3, 0 KOs).
