Los Angeles wide receiver Robert Woods caught six passes for 105 yards and another 14 on a carry of his own.Cowboys quarterback Dak Prescott was 25 of 39 for 266 yards and one touchdown, while Ezekiel Elliott rushed for 96 yards on 22 carries and a touchdown.The Cowboys (0-1) had one last drive starting with 2:35 remaining, but an offensive pass interference call on Michael Gallup negated a gain that would have put Dallas in field-goal position and created a third-and-20 from the Dallas 24. The Cowboys turned the ball over on downs with six seconds remaining.The Rams’ secondary made two key plays in the fourth quarter. Instead of trying for a game-tying field goal from inside of 30 yards early in the quarter, the Cowboys went for it on fourth down, but Los Angeles safety Jordan Fuller stopped Cowboys wide receiver CeeDee Lamb one yard short at 9-yard line.On the Cowboys’ next possession, cornerback Jalen Ramsey, who agreed to a five-year, $105-million deal Wednesday, prevented a third-down completion to Amari Cooper with just over five minutes remaining, and the Cowboys were forced to punt.The Rams’ offense got off to a fast start to the season, going 75 yards in seven plays on its first possession with Brown scoring on a 1-yard plunge up the middle. The Rams (1-0) moved the ball again on their second drive, which ended when rookie kicker Sam Sloman missed a 29-yard field goal.The Cowboys took advantage, driving the ball 80 yards in eight plays to tie the score 7-7 early in the second quarter on a 19-yard pass from Prescott to Elliott.
