The odds are against Green Bay Packers receiver Greg Jennings making the quick turnaround for Thursday night's game against the Chicago Bears, potentially leaving the Packers without their top receiver for a key NFC North matchup.

Jennings missed practice again Wednesday because of a groin injury and has been listed as doubtful on the Packers' final injury report of the week. Technically, that means he has a 25 percent chance of playing.

Coach Mike McCarthy, of course, left open the possibility that Jennings could be cleared for at least part of Thursday's game. Jennings worked with athletic trainers Wednesday, and McCarthy said he did not have feedback from that workout at the time he addressed reporters.

While Jennings can't be replaced, the Packers at least would be in position to credibly use their three- and four-receiver packages without him. Veteran Donald Driver is available to step into the rotation after sitting all but the three plays Jennings missed in last Sunday's 30-22 loss to the San Francisco 49ers. This is the precise reason why the Packers kept Driver on their roster despite his status on the depth chart.

We'll let you know of any further developments and will post a full injury report later Wednesday.
