The Chicago starting cornerback is in a sling after suffering an injury late in last week's loss to the Seahawks.
Jennings injured his shoulder in overtime of the game, and has been in a sling ever since as he attempts to return as quickly as possible. But it's still likely that Jennings will miss a few weeks recovering from the injury.
According to Jeff Dickerson of ESPN Chicago, the hope in Chicago's locker room was that Jennings could return before the end of the regular season. In the meantime, Kelvin Hayden is expected to start across from Charles Tillman, and D.J. Moore is likely to be activated to help shore up the depth in the secondary.
Chicago's defense has powered the team all season, but it faces its most adversity of the year heading into Sunday's game against the Minnesota Vikings. Chicago gave up back-to-back touchdown drives to Seattle at the end of regulation and in overtime on Sunday, and will now be without Jennings and Brian Urlacher, who is out three weeks with a hamstring injury.
