Hockenson (hand) isn't participating in Thursday's practice, Dave Birkett of the Detroit Free Press reports.
Since turning in a limited session last Wednesday due to a left hand injury, Hockenson hasn't taken any reps in any of the Lions' subsequent four practices. He was listed as doubtful before being placed on the inactive list for last week's loss to the Broncos, and unless he gets back on the field in some capacity Friday, Hockenson will likely carry a designation into this weekend's contest against Arizona, if he's not ruled out beforehand. Backup tight ends Shane Zylstra (63 percent of offensive snaps, six targets) and Brock Wright (55 percent, five targets) saw similar workloads and involvement in the passing game while Hockenson was sidelined in Denver.
