Smith, Setterstrom injuries troubling

One point Steve Spagnuolo hit on during our conversation Wednesday was the St. Louis Rams' need to avoid too many injuries.

The progress his team showed last season hit a wall when injuries and Richie Incognito's self-induced departure devastated the offensive line. With left tackle Jason Smith having already suffered a stress fracture to his toe, the Rams watched Friday as Mark Setterstrom, one of their key backups on the line, suffered an arm injury in practice.

Smith is expected to miss organized team activities and minicamps. We do not yet know how long Setterstrom might be out and there's still three months to go before the regular season. But any injuries are too many injuries for a team still trying to improve its depth.

Left guard Jacob Bell underwent knee surgery this offseason and should be ready for training camp.

Update: It's a torn triceps for Setterstrom. Season in jeopardy.
