ATLANTA (AP) — The matchups seemed to greatly favor Atlanta when the Falcons and Dolphins each turned to backup quarterbacks in the first quarter.

The Falcons' top backup was T.J. Yates, a fourth-year veteran with five career starts. The Dolphins' No. 2 quarterback was Seth Lobato, an undrafted rookie from Northern Colorado.

Lobato didn't appear to be rattled by the big stage, but he lost a late fumble inside the Atlanta 10 that ended Miami's comeback hopes in its 16-10 loss to the Falcons on Friday night.

Despite the turnover, Lobato may have surpassed the expectations of some in the preseason opener for both teams.

"Considering everything, I thought he did a good job," Dolphins coach Joe Philbin said. "I thought he had poise and good command of what we were doing."

Lobato led Miami to the Atlanta 5-yard line with less than 3 minutes remaining before fumbling a shotgun snap. Defensive end Nosa Eguae recovered for Atlanta.

"As a quarterback, I have to make that play and can't let the ball get on the ground in that situation," said Lobato, who took over after Ryan Tannehill opened the game with a touchdown drive.

Lobato completed 14 of 28 passes for 124 yards.

"I felt really comfortable and thought the line did a great job protecting me," Lobato said.
