The Chicago Bears will be without two of their top offensive players this weekend.

Bears head coach John Fox officially ruled out QB Jay Cutler for Sunday with a hamstring injury, and also announced WR Alshon Jeffery would miss Sunday as he’s still dealing with a hamstring injury.

According to a number of reports, Cutler is expected to miss at least two weeks with his hamstring injury.

Jimmy Clausen will step in at quarterback for Cutler while Marquess Wilson will draw into the starting lineup in place of Jeffery.

Clausen went 14-23 for 121 yards and an interception in relief of Cutler last week.
