In his first game as the Dolphins’ starting quarterback, Tannehill went 11 for 27 for 112 yards and one interception, and Miami lost to the Atlanta Falcons 23-6.
Four of Tannehill’s passes were dropped, including a potential 4-yard touchdown throw that Anthony Fasano bobbled in the end zone. Tannehill was sacked once, forced to run twice and hit several other times.
Miami fell to 0-3, and Atlanta improved to 1-2.
The Dolphins managed only three points in Tannehill’s seven possessions. Atlanta’s first-team offense couldn’t muster a touchdown, either, until Miami’s defensive starters left the game at halftime.
Matt Ryan played midway into the third quarter and went 18 for 26 for 220 yards, including a 20-yard touchdown to Roddy White against reserves.
Both teams played their starters for the entire first half, when the Falcons outgained the Dolphins 175-166 and took a 9-3 lead.
Dominique Davis, an undrafted rookie free agent bidding to become Ryan’s backup, hit Tim Toone deep for a 39-yard score in the fourth.
Ryan led Atlanta 66 yards for a touchdown against backups. Michael Turner carried 10 times for 35 yards, and Julio Jones made four catches for 90 yards.
The Dolphins’ No. 1 defense got off the field without giving up points for the first time this exhibition season by stopping the Falcons on downs on the opening series. Cameron Wake finished with 1½ sacks for Miami.
The final eight minutes were played in heavy rain.
