Cardinals' Tanner Vallejo: Activated, should return Sunday

Vallejo (knee) mwas activated from the IR/designated for return list Saturday.

Vallejo hasn't played since Week 10 and the injury couldn't have come at a worse time for him, as he was starting to earn a bigger role on defense. He should be available for Arizona's final two games of the regular season, but it remains to be seen what kind of role he'll have.
