Analysis:

Campbell cleared a major hurdle on his road back Thursday, practicing for the first time since suffering a slight MCL tear Oct. 5 against Denver. He stressed that he doesn't want to return to the field unprepared, but Campbell remains cautiously optimistic about playing Sunday against the Eagles, a proposition which seems realistic barring a setback. Coach Bruce Arians said previously that Campbell would need to log at least one practice in order to play in Week 8.
