ARLINGTON, Texas (AP) - Cooper Rush won again filling in for Dak Prescott, throwing a touchdown pass to Michael Gallup in the receiver's 2022 debut as the Dallas Cowboys beat the Washington Commanders 25-10 on Sunday.
Rush also had a TD toss to new No. 1 receiver CeeDee Lamb while improving to 4-0 in his career as a starter.
The three Rush-led victories this season for the Cowboys (3-1) have been since Prescott fractured the thumb on his throwing hand when the defending NFC East champs lost their opener to Tampa Bay.
The Commanders (1-3) lost a third consecutive game in Carson Wentz's reunion with an old division rival from his days as the No. 2 overall pick by Philadelphia.
Washington had several promising drives stalled by penalties, and flags also wiped out interceptions by Benjamin St.-Juste and Kamren Curl.
The Commanders finished with 11 penalties for 136 yards after totaling 128 penalty yards the first three weeks.
Prescott had the same role from the previous home game, wearing a headset while cajoling the crowd for the defense, which is the first for Dallas to hold the first four opponents to 19 or fewer points since 1973.
Gallup returned exactly nine months after tearing the anterior cruciate ligament in his left knee on a Jan. 2 touchdown catch in 25-22 loss to Arizona in Week 17 last season.
The 9-yard catch from a scrambling Rush for a 12-7 second-quarter lead came in the same end zone as the injury. Then Gallup grabbed Lamb in a bear hug before celebrating with other teammates.
The Cowboys believed Gallup's return would help Lamb in his role leading the group after the offseason trade of Amari Cooper to Cleveland in a cost-cutting move. For one game at least, they were right.
Lamb had three consecutive catches for 56 yards on a first-half drive to the second of Brett Maher's four field goals.
The third-year pro fooled the defense with a nice fake on a slant for a 30-yard score and a 22-10 lead on the first play of the fourth quarter.
Lamb had six catches for 97 yards a week after he scored the go-ahead TD in a victory at the New York Giants. Gallup had two grabs for 24 yards while drawing pass interference penalties of 38 and 27 yards.
Wentz was flagged for intentional grounding twice a week after being sacked nine times. He threw two interceptions, the second all but clinching the Dallas victory in the fourth quarter.
Jahan Dotson had a 10-yard touchdown catch that gave Washington a 7-6 lead in the second quarter.
Washington owner Dan Snyder, under investigation by the NFL over alleged workplace misconduct within his club, was on the field before the game with Cowboys owner Jerry Jones. Snyder is suspended from day-to-day operations and hasn't been seen in public at Commanders home games.
