First quarter: Cowboys 7, Rams 0

ARLINGTON -- After one quarter at Cowboys Stadium, Dallas leads St. Louis, 7-0.

Murray off to fast start: Tashard Choice got the start with Felix Jones out with a high ankle sprain, and Choice and rookie DeMarco Murray were expected to share the carries. On the third official play of the game, Murray scored on a 91-yard touchdown run, the second-longest in franchise history. There was good blocking up front and Murray read his holes well and made a move on veteran safety Quintin Mikell, who got turned around. Coming into the game, Murray had 71 yards on 24 carries.

Penalties, penalties, penalties: Penalties are not acceptable for any NFL team. Last week, the Cowboys had a season-high 10. In the opening quarter vs. the Rams, the Cowboys were flagged three times for 19 yards. There were two offsides calls against the defense and a holding call on fullback Tony Fiammetta.

No Bradford: A.J. Feeley made his first start of the season with Sam Bradford out with an ankle injury. Feeley was able to convert one third-down play and took the Rams into Cowboys territory just once in the first quarter.

Forcing turnovers: The Cowboys need to force turnovers to win games, though last week the defense got four in a loss to the New England Patriots. Safety Abram Elam forced a fumble when he threw his shoulder into Cadillac Williams on the end of a screen pass. Elam's forced fumble and recovery came with 39 seconds to play. But it came with a price. Rams right tackle Jason Smith suffered an injury on the play and was taken off the field by stretcher. Smith, a Dallas native who attended W. T. White High School, had his head hit Elam's hip as he dived at Elam's legs.
