Jennings (ankle) doesn't have an injury designation for Sunday's game at Minnesota, Tom Pelissero of NFL Network reports.
Jennings was listed with an ankle injury ahead of Week 1 and even made a brief exit from Monday's win over the Jets, but it didn't stop him from catching each of his five targets for a team-high 64 receiving yards. He played 47 percent of San Francisco's snaps on offense and ran a route on 56 percent of the pass plays, filling his usual role as the No. 3 receiver behind Deebo Samuel and Brandon Aiyuk. It is possible Jennings benefits from a few extra snaps here and there if Samuel continues to get some work as a running back while Christian McCaffrey (Achilles) is out.
