Jennings (ankle) practiced in full Saturday and doesn't have an injury designation for Monday night's season-opening matchup with the Jets.
Jennings was limited in San Francisco's first two practices of the week due to an ankle issue but appears to be good to go for the team's regular-season opener Monday after practicing in full Saturday. The 27-year-old is slated to fill the 49ers' No. 3 wideout role behind star pass catchers Deebo Samuel and Brandon Aiyuk, though Jennings could see a bit more attention Monday due to Aiyuk not being expected to handle a full workload after sitting out most of training camp while pushing for a contract extension.
