Green Bay Packers linebacker Brandon Chillar's shoulder injury may keep him out for the remainder of the season, reports Rob Demovsky of the Green Bay Press-Gazette.

"I hope it isn’t season-ending, don’t think it is, but I’m not going to rule out that it’s not possible," James Ivler, Chillar's agent, told Demovsky. "By Wednesday, we’ll probably have a better idea."

Chillar (6-3, 237) started the 2010 season-opener and had 11 tackles and an interception during the first three games before he was injured last Monday night against the Chicago Bears.

Demovsky adds that an MRI on Chillar's shoulder, which kept him out of Sunday's win over the Detroit Lions, was inconclusive.
