ST. LOUIS (AP) -- The St. Louis Rams have placed rookie Fendi Onobun on injured reserve with a back injury that didn't respond to treatment.
Onobun, a sixth-round pick, had two receptions for 15 yards. He was drafted as a long-range prospect after playing only one season in college at Houston.
The Rams signed tight end Derek Schouman, who was released from injured reserve by the Bills with a knee injury in September.
Coach Steve Spagnuolo said Wednesday the team didn't want to push it any longer with Onobun, who had missed the previous four games.
Offensive tackle Rodger Saffold had limited work coming off an ankle injury. Wide receiver Danario Alexander returned from minor knee surgery that sidelined him for three weeks, although Spagnuolo said the team would be cautious.
