Campbell had to sit out last week's loss to Jacksonville and was replaced by Weeden, who started and was concussed at some point against the Jaguars. Weeden has not yet been given permission to practice.
The Browns signed free agent Caleb Hanie earlier this week in case Campbell or Weeden can't play. Alex Tanney was signed last week off Dallas' practice squad, and he and Hanie split the plays with Cleveland's starting offense in Wednesday's practice.
Turner said both young quarterbacks have made progress and can be counted on in case Campbell is unable to play.
