The Ravens' secondary absorbed its latest blow Monday when cornerback Asa Jackson was declared out for the season.
A second opinion confirmed the initial diagnosis from Sunday that Jackson had damaged his posterior cruciate ligament. Because the injury would take five weeks to recover from, the decision was made to shut him down.
Both Jackson and rookie free safety Terrence Brooks, who injured his medial collateral and posterior cruciate ligaments Sunday while covering a kickoff against the Jacksonville Jaguars, will be placed on injured reserve this week.
Although cornerback Rashaan Melvin had a solid game in relief of Jackson and the Ravens signed veteran corner Antoine Cason last week, they're still expected to look for reinforcements.
"I don't think you can ever feel like you have enough depth to get you through, so we'll be looking at all our options," Ravens coach John Harbaugh said. "It's one thing to hope to have a guy. It's another thing to find a guy. So, we're just looking at our options right now as we speak and we'll have some answers probably over the next two days on that."
Jackson will join four other cornerbacks previously placed on injured reserve, including Jimmy Smith (Lisfranc foot), Danny Gorrer (knee ligaments), Tramain Jacobs (pulled hamstring) and Aaron Ross (torn Achilles). Cornerback has been something of a cursed position for the Ravens this season in terms of injuries.
"We don't have time to worry about it, but it seems that way," Harbaugh said. "In teams, it seems like it comes in bunches at certain positions, certain types of injuries. Whether it's with a team or around the league, I've definitely seen that. It feels that way, yes."
Jackson led the Ravens with eight tackles Sunday, and he also had two pass deflections Sunday. This marks the second time this season Jackson has been placed on injured reserve after previously spending time on injured reserve-designated to return with a severe toe sprain.
"I've been in that position a lot, I've been the one that went down," said cornerback Lardarius Webb, who's dealt with a lower back problem all season and has torn both anterior cruciate ligaments in previous season. "I'm here to keep them positive. So, it's next man up again."
