John DeFilippo said he's unsure if the Cleveland Browns have their quarterback already on the roster.

DeFilippo was hired this week as offensive coordinator.

"We're not sure if our starting quarterback is in the building right now or not," said DeFilippo, who was hired Wednesday to replace Kyle Shanahan. "If he is, great. If he's not, that's great too."

Mike Pettine said the Browns will continue evaluating the roster and discussing all positions over the next few weeks.

DeFilippo met Johnny Manziel before last year's draft and said he's ready and eager to work with him.

"He flew out to Oakland and [I] spent a day with him," DeFilippo said. "Can you get an overview on a guy in a day? No. But you can get a grasp of what he thinks and how he's feeling and those things."
