ST. LOUIS -- Safety Oshiomogho Atogwe, the Rams' second-leading tackler, was placed on injured reserve Wednesday with a dislocated shoulder and will miss the rest of the season.
Atogwe, a five-year veteran, was hurt on the final play of the first half in Sunday's loss at Chicago when he was hit by Bears running back Matt Forte's helmet while assisting on a tackle. Atogwe has 74 tackles, two interceptions, three forced fumbles and two fumble recoveries this season and had started 60 consecutive games dating to the 2006 opener.
Rookie offensive tackle Jason Smith met with an independent consultant Tuesday and underwent an MRI exam that showed no problems beyond a concussion that has sidelined him two games. Smith has failed three tests that showed he's still experiencing symptoms, the latest on Monday.
"It was just more of a reassurance thing," Spagnuolo said.
Atogwe held out hope on Monday that he could finish the season wearing a brace, but the team decided against it. Spagnuolo said the risk was too great for an injury that will require surgery.
"I really couldn't probably sleep or live with myself if O.J. forced himself in there and all of a sudden that thing popped out again," Spagnuolo said. "There was a chance that was going to happen. For his health and his career, I think it's best."
Both of the backup quarterbacks behind Kyle Boller played in NCAA Division II and faced each other in the playoffs last November. Keith Null was a sixth-round pick out of West Texas A & M, and Reilly was undrafted after playing at Central Washington.
"It's kind of few and far between that you run into somebody that played at Division II, let alone somebody you played against," Reilly said. "I think no matter where you are, you've got to prepare as if you're going to play."
Spagnuolo said the signing had no relation to starting quarterback Marc Bulger's recovery from a fractured left shin bone. Bulger has missed two games, was still on crutches earlier in the week and was scheduled for a follow-up MRI exam.
"Oh yeah, I was shocked," Hart said. "Normally, they don't cut the starter. But this is an opportunity."
