Turley hopes to play this week
"Preliminary tests so far have been fine, so I don't see why I shouldn't be cleared to play on Sunday," Turley said. "But you never know. This is a unique situation and you don't want to treat it too lightly."
Turley, in his sixth season, sustained the first concussion of his career when he was accidentally kicked in the back of the head on the last play of the third quarter of Sunday's 34-24 victory over the Packers.
Turley said he doesn't remember any of the fourth quarter.
"It's better every hour of the day," Turley said. "Hopefully, the next test I take everything will be fine and they'll clear me."
Running back Lamar Gordon, who missed most of Sunday's game with a high ankle sprain, was listed as questionable. He said the ankle is a much larger concern than a sprained left wrist that has bothered him off and on.
"I could play with the wrist, I'd just put the ball in my right arm," Gordon said. "But I can't run on one leg. The ankle is really bothering me right now."
The Rams said Gordon also sustained a mild concussion on the hit that knocked him out of the game. He didn't think so, and said his response to a game-plan quiz administered by Marshall Faulk proved he was fine.
Martz said third-stringer Arlen Harris would start against the Steelers. Harris had 85 yards on 18 carries and a 3-yard touchdown run against the Packers.
