The Cowboys began their 2008 campaign on the road against the Cleveland Browns.  In the first quarter, Dallas got the first shot as RB Marion Barber got a 1-yard TD run.  In the second quarter, the Browns would respond with QB Derek Anderson completing a 2-yard TD pass to TE Kellen Winslow.  Afterwards, the Cowboys responded with QB Tony Romo completing a 35-yard TD pass to WR Terrell Owens, along with another 1-yard TD run from Barber.  In the third quarter, Dallas pulled away with rookie RB Felix Jones getting an 11-yard TD run, which was his first carry in the NFL.  In the fourth quarter, Cleveland's only response would be kicker Phil Dawson's 34-yard field goal.
