Jennings (ankle) practiced on a limited basis Thursday, Adam Caplan of SiriusXM NFL Radio reports.
With back-to-back capped sessions under his belt following the ankle injury that he sustained in the season opener against the Jets, Jennings has only one more chance to get back to full before potentially heading into the weekend with a designation for Sunday's contest at Minnesota. Assuming he's active Week 2, he'll continue to serve as the 49ers' No. 3 WR behind starters Deebo Samuel and Brandon Aiyuk.
