EARTH CITY, Mo. -- The St. Louis Rams made some roster moves Friday as their injury report indicated a need for another safety. So the Rams released cornerback Brandon McGee and called up safety Christian Bryant from the practice squad.

While McGee could have helped on special teams, Bryant gives the Rams the help on special teams while also serving as depth at safety. That depth is apparently more important for the Rams than depth at corner this week because safety Maurice Alexander is out this week because of a groin injury.

As expected, the Rams probably will have the services of receiver Kenny Britt and linebacker James Laurinaitis. Britt and Laurinaitis sat out Tuesday and Wednesday because of shoulder soreness and non-injury related reasons, respectively.

Elsewhere, the Rams are mostly status quo though they added running back Benny Cunningham to the report after he sat out Friday with knee soreness. Cunningham is also listed as probable to play.

The Rams also signed cornerback Eric Patterson to the practice squad to replace Bryant.

Here's Friday's full injury report:

Out: DE Eugene Sims (knee), S Maurice Alexander (groin)

Doubtful: RB Chase Reynolds (knee)

Probable: WR Kenny Britt (shoulder), LB James Laurinaitis (not-injury related), RB Benny Cunningham (knee)
