How long is Lamar Jackson out? Latest news, updates on Ravens' QB's hamstring injury

With injuries already piling up on Baltimore's defense, star quarterback Lamar Jackson exited a Week 4 loss to the Kansas City Chiefs with an apparent hamstring injury. Not only did Baltimore lose the game to fall to 1-3, but it also lost its franchise QB in the process.

Jackson remained on the sidelines after he was taken out, but there is an understandable level of concern around the team as it faces an uphill battle with a hobbled QB.
