St. Louis quarterback Marc Bulger suffered a concussion in Sunday's 24-19 loss to Seattle, and coach Scott Linehan said it was too early to know if he'll be available for next week's game against Atlanta.
Bulger left after making a shovel pass midway through the first quarter. He was hit by several players, but threw a pass that was intercepted by defensive end Patrick Kerney. But coach Scott Linehan said Bulger was initially hurt on the Rams' first possession on a blindside sack by linebacker Leroy Hill.
"He didn't seem quite right on the sidelines," Linehan said. "We talked a little bit, and I could tell by looking at him right when he walked off that something was different.
"He mentioned that he didn't feel good, and that is a big concern. He said he was starting to feel nauseous."
Bulger, who missed two games earlier this season with broken ribs, walked on his own to the locker room. He was replaced by Gus Frerotte.
The starting QB has taken a beating behind an offensive line decimated by injuries this season. Bulger, who was 3-for-5 for 32 yards and the one interception, has been sacked 30 times this season.
Bulger has completed 61 percent of his passes with six touchdowns and nine interceptions in what has been a disappointing season after he signed a six-year, $65 million contract extension on the first day of training camp. That deal made him the highest-paid player in franchise history. The contract included $27 million in guaranteed money and put him in a group of six quarterbacks making $10 million annually.
St. Louis' problems on the offensive line began in Week 1 when left tackle Orlando Pace was lost for the season with a torn triceps, the first of several linemen to be hurt. The Rams have used 15 line combinations this season.
Bulger was among several players hurt Sunday.
Center Brett Romberg also left in the first quarter with an ankle injury and did not return. He missed three games earlier this season with injuries to both ankles. His status for next week was not known.
Rams linebacker Pisa Tinoisamoa left in the third quarter with a sprained left knee and will have an MRI Monday.
Seattle wide receiver D.J. Hackett hurt his right ankle in the third quarter. Coach Mike Holmgren wasn't sure when he would return.
Hackett suffered a high right ankle sprain in the season-opener against Tampa Bay and missed six games. He entered Sunday's game questionable with a knee injury.
Hackett had four catches for 41 yards against St. Louis. He had a career-best nine catches for 136 yards and a touchdown last week against the Bears.
