Miami Dolphins rookie quarterback Ryan Tannehill has left the team's game against the Miami Dolphins with an injured left knee and quadriceps muscle and his return is questionable.
Tannehill appeared to be hurt on a sack on third down by Calvin Pace on the Dolphins' second possession of the game. He limped off the field and was replaced on Miami's next series by Matt Moore.
Tannehill remained on the sideline trying to stretch out his left leg and jogging, and appearing to be in some pain as he hopped after putting some weight on the leg.
