LAKE FOREST, Ill. -- Tim Jennings' right arm remained in a sling Tuesday as the Chicago Bears cornerback continued to receive treatment for a shoulder injury he suffered late in the team's 23-17 overtime loss to the Seattle Seahawks.

Jennings, who leads the NFL with eight interceptions, hurt the shoulder when he tried to tackle Seahawks' fullback Michael Robinson on the Bears' sideline in overtime. Jennings missed the final eight plays of the overtime period and then left the locker room in a sling to help immobilize his injured right shoulder.

Jennings is not the first Bears' defensive back to deal with a shoulder issue this season. Starting free safety Chris Conte suffered a shoulder dislocation early in the preseason and was forced to sit out a couple of weeks before returning in time for the regular season opener versus the Indianapolis Colts.

Bears head coach Lovie Smith did not provide a timetable for how long Jennings would be out when he addressed the media on Monday, but there was optimism in the postgame locker room that Jennings could return before the end of the regular season.

In the meantime, veteran cornerback Kelvin Hayden is in line to replace Jennings in the starting line-up Sunday against the Minnesota Vikings, while D.J. Moore could be activated to handle the nickel back duties. With Moore a healthy inactive versus Seattle, the Bears used Zack Bowman at cornerback in their nickel package for three plays in overtime after Jennings got hurt, with Hayden moving inside to cover the slot.

With Brian Urlacher reportedly out for the at least the next three weeks due to a hamstring strain, Jennings would be another key loss for the Bears' defense as the team tries to solidify a playoff spot.
