Mayer recorded two receptions on two targets for 20 yards in Saturday's 31-16 loss to the Cowboys.
Mayer participated in his second consecutive preseason contest and saw run into the early second quarter. He showed rapport with Aidan O'Connell on a 13-yard connection, his longest gain of the exhibition schedule. It's possible that veteran Austin Hooper plays ahead of Mayer to start the regular season, but the rookie should have a significant role in the offense.
