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.
Rams coach Steve Spagnuolo said Monday that Dahl would undergo testing Tuesday and judged him day to day.
Defensive tackle Clifton Ryan was held out even though Spagnuolo said the lineman had been feeling better after migraines. The team is receiving a second opinion this week, although a league source told NFL Network insider Jason La Canfora on Sunday that Ryan is suffering from post-concussion symptoms.
