Jennings (oblique) is practicing in a limited capacity Thursday, Cam Inman of The San Jose Mercury News reports.
Jennings continues to manage an oblique injury he's dealt with since mid-August. With Ricky Pearsall (chest/shoulder) to miss at least the first four games of the year while on the reserve/non-football injury list, Jennings has an opportunity to work as the clear No. 3 receiver behind Deebo Samuel and Brandon Aiyuk, health permitting. He'll have two more chances to increase his participation level prior to Monday's regular-season opener at home against the Jets.
