Dallas moved into $1.2 billion Cowboys Stadium, a massive structure with a retractable roof and the world's largest scoreboard that hangs over the field.
That scoreboard, however, could prove troublesome because several punts struck it during pre-game practice and another hit it during the game itself. When that happens, the officials declare it a dead ball and the play is run over -- something that could happen many times once the regular season begins.
Romo played the entire first half, completing 18-of-24 passes for 192 yards without an interception. He guided scoring drives of 90 and 79 yards that led to 1-yard touchdown runs by Marion Barber and Felix Jones.
The touchdown by Jones came with 1 second left in the first half and gave Dallas a 14-10 lead.
Tennessee's Kerry Collins was 8-of-11 for 55 yards. He threw a touchdown pass of 17 yards to Justin Gage in the second quarter.
