Lamar Jackson's injury is not season-ending, but Ravens still have issues

Jackson was injured in the first half of Sunday's 10-9 win over the Denver Broncos and did not return for the second half with a knee injury. 

He was sacked twice in the first half, with the second one resulting in an injury that hobbled him as he walked off the field. He needed assistance to climb the steps in the tunnel to lead to the team's locker room.

Harbaugh said Jackson will undergo more tests on Monday to help determine his timeline, but at this point it is something that could be "days" or "weeks" for Jackson. 

With an 8-4 record the Ravens are still in a pretty good spot in the playoff race, especially with a remaining schedule that only has one team with a winning record (Week 18 against Cincinnati), but they have to be concerned about the way the season has been trending over the past few weeks.

Two weeks ago they barely snuck out of Carolina with an ugly 13-3 win against a bad Panthers team, and then last week allowed another double-digit fourth quarter lead slip away in a 28-27 loss to the Jacksonville Jaguars. 

With Jackson sidelined for most of Sunday's game, the offense looked sluggish with Tyler Huntley under center and was fortunate to sneak away with an ugly win over a bad Broncos team when Brandon McManus' 62-yard field goal attempt at the end of regulation fell short. 

It is not the way a potential Super Bowl contender wants to be playing this late in the season, and now with Jackson injured and his status not yet known for the short-term things might start getting a little tight for the Ravens down the stretch.
