Both Campbell and Weeden are recovering from concussions that they have sustained in recent matches, meaning that the Browns are using veteran Caleb Hanie and new signing Alex Tanney in practice in case either needs to start against the New England Patriots on Sunday.
Chudzinski told the team's official website: "Right now, as we stand, Campbell and Weeden have both been cleared for activity, but not for practice. It's too difficult to know exactly when they'll be cleared through the process.
"We'll tailor the package to whichever guy ends up being the starter to what they can do and to what is going to be effective, hopefully, versus New England.
"I think we'll get a better sense though, as we get into practice and Hanie and Tanney are getting the reps, and we can go either direction once we get into that and get a feeling one way or the other. At this point, I will keep all the options open."
