Browns quarterback Jason Campbell has been cleared to practice after sustaining a concussion and could play Sunday against New England.

Campbell will practice Thursday, and as long as he passes a concussion test by an independent neurologist, he may be able to face the Patriots. Campbell was injured on Nov. 24 against Pittsburgh. He was replaced last week by Brandon Weeden, who started and was concussed at some point during the loss to 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.

Browns coach Rob Chudzinski said he was "encouraged" by Campbell's progress.
