"The St. Louis Rams expect to be without starting receiver Donnie Avery for four to six weeks after the second-year pro suffered a foot injury, coach Steve Spagnuolo told reporters Sunday.

An MRI showed more significant damage than expected after Avery experienced soreness in his left foot Saturday morning, the St. Louis Post-Dispatch reported.

The Rams lack established depth at wide receiver. Keenan Burton, Ronald Curry and Laurent Robinson appear to be the top three options beyond Avery."
