Rams Pro Bowl running back Steven Jackson underwent back surgery in early April to repair a herniated disc he suffered in late November of last season.
"It was a minor procedure," coach Steve Spagnuolo told the Post-Dispatch on Tuesday evening. "He feels great. It's really not a big deal."
But Spagnuolo did say Jackson probably would be held out of at least the start of organized team activities — the full-squad practice sessions that begin May 18 at Rams Park. "Just to be sure," Spagnuolo said.
And there's a chance Jackson could be held out of practices until the start of training camp at the end of July.
