The San Francisco 49ers and wide receiver Jauan Jennings remain without an agreement amid ongoing contract negotiations, Tim Kawakami reported Tuesday for the San Francisco Standard.

HC Kyle Shanahan said he expects Jajuan Jennings (calf) to be ready for Week 1. WR Jacob Cowing and CB Jakob Robinson could be put on IR.

The San Francisco 49ers and Jauan Jennings might have reached an impasse. In the face of yet another contract dispute with a wide receiver, the Niners have been carefully trying to avoid the public perception of an actual dispute.
