MIAMI GARDENS, Fla. (AP) -- Ryan Tannehill threw for 145 yards in less than a half despite working behind a makeshift offensive line, and the Miami Dolphins beat the Atlanta Falcons 13-9 in an exhibition game Saturday night.

While Tannehill wasn't touched, counterpart Matt Ryan was sacked three times in four series.

Miami center Mike Pouncey left in the first half because of a knee injury, leaving the Dolphins (1-2) with only two starting offensive linemen at their regular positions. Pouncey limped to the locker room shortly before halftime and didn't return.
