Tests conducted on Ravens starting cornerback Lardarius Webb's lower back revealed no structural damage, according to sources.
Webb's back injury, which was suffered last Friday and has sidelined him since the second day of training camp, is apparently muscular.
The team is expected to be cautious with Webb to avoid this becoming a chronic, long-term injury. Webb's availability for practices will be evaluated on a day-to-day, week-to-week basis.
At this point, the injury isn't expected to affect Webb in the regular season and is expected to get better with rest and rehabilitation.
Webb left practice early Friday after bending over at the waist in pain.
The injury was initially described as minor by coach John Harbaugh, but the team became more concerned about the severity of the back injury in recent days and opted for further evaluation.
"He's got some back things that we're looking at right now," Harbaugh said of Webb following a practice Monday night at M&T Bank Stadium "Backs are a little weird. At first, it was no big deal. It's lingering a little bit, so we'll find out what's going on with it."
Webb is entering the third year of a five-year, $50 million contract that includes $15 million in guaranteed money. He recorded 74 tackles, 22 pass deflections and two interceptions last year, his first year back after tearing his anterior cruciate ligament in October 2012 while covering Dallas Cowboys star wide receiver Dez Bryant.email@example.com
