Pettine said the team will make a decision on who will be under center Week One in Pittsburgh no later than the third preseason game, and maybe even sooner.
"It'll be before the third preseason game. I just don't have a date. I don't know if I'll set a date and kind of paint ourselves into a date, but it will be sooner than the third preseason game," Pettine said.
The Browns will play that third preseason game in Cleveland against the St. Louis Rams on Aug. 23.
Pettine did not yet say who would start the first two preseason games -- at Detroit and Washington - at quarterback.
