NFL: Romo looks OK, but Cowboys fall to Ravens
The Ravens (2-0) also got a 26-yard fumble return for a TD when Courtney Upshaw picked up a botched handoff from Romo and stayed on his feet while Romo tried to drag him down by his jersey.
Romo's final play was a 31-yard touchdown pass to Dez Bryant midway through the first quarter.
Baltimore led 14-7 before Flacco took the field for the first time. He threw a 19-yard scoring pass to Torrey Smith for a 24-10 lead late in the first half.
A first-round draft pick by Pittsburgh in 2006, Holmes was the Super Bowl MVP in his third year. He had his best season statistically the following year, 2009, with 79 catches for 1,248 yards and five touchdowns.
He was traded to the New York Jets the following offseason.
The Jets released the 30-year-old Holmes in March after he had 23 catches - the second-lowest total of his career - for 456 yards in 11 games.
Manziel: Not ready yet. As Johnny Manziel prepares for Cleveland's exhibition on Monday night in Washington, a game that could decide whether he or Brian Hoyer is the Brown's starting quarterback for the season opener at Pittsburgh on Sept. 7, the rookie acknowledged he's still got a lot to learn.
"I don't think I'm ready for Pittsburgh right now," he said Saturday.
Manziel, though, was quick to point out that he's made progress during training camp, and he expects to get better running Cleveland's offense.
Manziel and Hoyer will split time with Cleveland's first-team offense against the Redskins in a game being hyped as a nationally televised matchup between Johnny Football and RG3, Washington quarterback Robert Griffin III.
Hoyer, who entered camp as the No. 1 quarterback and has done nothing to lose his starting job, was unaware that he's not part of the ratings campaign.
"I don't watch ESPN," he said.
