Kirk (undisclosed) is returning to practice Thursday, Josh Weinfuss of ESPN.com reports.
Kirk has been out since the weekend with a minor, undisclosed injury. A few missed days shouldn't make much difference as he enters his third season in coach Kliff Kingsbury's system, though Kirk presumably is preparing for more slot work after the Cardinals signed A.J. Green (undisclosed) in the offseason. Green is now the one missing practice with a minor injury.
