UPDATE: It's not all bad for the Ravens.
While both Asa Jackson and Kapron Lewis-Moore went down in practice on Sunday, Jackson's injury is apparently not that serious.

The No. 1 spot the Ravens cannot afford injuries would be at cornerback.

Jackson is coming off a solid performance against the 49ers on Thursday, which included a well-played interception in zone coverage. Jackson has appeared to be leading for the third cornerback spot for the past week or so, and losing him would be devastating to a team that doesn't have many options behind him.
Chykie Brown has struggled all preseason and Dominique Franks is still learning the system after missing the first few days of training camp due to failing the conditioning test.
John Harbaugh is expected to address the media around 2:45 p.m. and an update could be given at that time.
