A return to full strength for the Bucs defense will have to wait at least another week, with LB Kwon Alexander (hamstring) and S Keith Tandy (hip) and two others ruled out for Sunday's game at Arizona.

But two other key defensive starters could return, as LB Lavonte David (ankle) and S T.J. Ward (hip) were listed as questionable. Both remained at limited participation in Friday's practice.

The others ruled out: special teams captain Josh Robinson (concussion) and DE Ryan Russell (shoulder). There was encouraging progress for C Ali Marpet (illness) and DE Robert Ayers (back), who were upgraded to full participation but were listed as questionable.
