The two latest Ravens to be banged up at training camp appear to be Center David Hale and Defensive Tackle Haloti Ngata. According to reports, the two were participating on head-to-head drills and went down after colliding.
Hale had to be carted off the field and Ngata went down holding his arm/wrist. Ngata did return to practice, but did not participate in any drills. Hale was able to move his neck, but his status is still unclear.
Remember that Haloti Ngata dealt with back spasms last week, this appears to be a separate injury but also a less serious one.
