Jennings (ribs) didn't partake in practice Wednesday, the Vikings' official site reports. Jennings sustained a rib injury in Sunday's game in Chicago, but the ailment didn't stop him from returning to action. However, he mustered his worst performance of the season -- one catch (on two targets) for four yards -- which was likely precipitated by the injury. As a result, monitor his activity level in drills throughout the week to learn his potential availability Sunday versus the Packers.
