St. Louis Rams tight end Billy Bajema will be sidelined two to four weeks with a knee injury and defensive lineman Darell Scott has a high ankle sprain that also could put him out for as long as a month.

The Rams also lost safety Craig Dahl (concussion) and offensive tackle Rodger Saffold (back) during a 16-14 loss at Oakland on Sunday.

Coach Steve Spagnuolo said Monday that Dahl would undergo testing on Tuesday and judged him day to day.

Defensive tackle Clifton Ryan (migraines) was held out even though Spagnuolo said that Ryan had been feeling better. The team is getting a second opinion this week.
