Tannehill completed 2 of 4 passes for 8 yards with no touchdowns or interceptions in Friday's 27-10 preseason victory over the Giants.
The 28-year-old connected on his first two passes to Jarvis Landry and Kenny Stills, respectively. Tannehill then misfired on back-to-back throws to Jay Ajayi on the Dolphins' second possession before his exit from the game. It was reasonably positive debut for the fifth-year signal-caller in new head coach Adam Gase's offense, and he's expected to see more extended action in next week's tilt versus the Cowboys.
