Cook was limited at Wednesday's practice with a back injury, Adam Caplan of SiriusXM NFL Radio reports.

Cook has logged at least 48 percent of the offensive snaps in four of the last five games, during which he accumulated 16 catches (on 25 targets) for 231 yards and touchdowns. That amounts to a healthy 9.2 yards per target, but now a back issue is affecting his practice reps. Cook has two more chances to prove his health ahead of Sunday's divisional-round game versus the Buccaneers.
