Jake Long likely to play against Arizona

EARTH CITY, Mo. -- St. Louis Rams left tackle Jake Long has cleared the concussion protocol and looks poised to return Sunday against the Arizona Cardinals.

After suffering the head injury last week against San Francisco, Long began the process required to return from the concussion soon after. He didn't practice Wednesday and was limited Thursday before taking part in Friday's practice at full speed. On the team's official injury report, Long is listed as probable for Sunday.

"I'm feeling great now and I'm ready to get back in," Long said Friday afternoon.

Long's impending return combined with the potential for normal starting right guard Harvey Dahl to get back in the mix could create some interesting offensive line permutations against the Cardinals. Dahl has been out with a knee injury, but practiced all week and is also listed as probable. That leaves something of a logjam on the offensive line given the success of Rodger Saffold at right guard in Dahl's stead.

The Rams could opt to rotate Saffold into multiple spots or potentially rotate Dahl in, but either way, they have some choices to make in terms of the offensive line for this one.

Elsewhere on the injury report, linebacker Daren Bates also received clearance from concussion protocol and is likely to return this week.

Here's the full Friday injury report:

Out: Center Scott Wells (leg)

Questionable: Cornerback Brandon McGee (foot)

Probable: Long (concussion), Bates (concussion), Dahl (knee), defensive end Eugene Sims (neck)
