Coach Bruce Arians said that Mickens (hip) was held out of Wednesday's practice and is considered day-to-day, Scott Smith of the Buccaneers' official site reports.
Mickens was ruled out for the remainder of Sunday's contest against the Falcons after picking up a hip injury. The 27-year-old has been Tampa Bay's primary return man so far this season. Giovani Bernard and Scotty Miller each returned kicks against Atlanta after Mickens left the contest, so expect them to share the return duties in Week 3 if he is unable to suit up.
