Greg Jennings Injury: Update on Green Bay Packers Star's Knee Injury

Green Bay Packers star receiver Greg Jennings suffered a knee injury early in the third quarter against the Oakland Raiders on Sunday and had to be carted off the field.

After a play in the third quarter, Jennings was noticeably hobbling off the field and had to be helped by teammates on the sideline.

Jennings' loss would hurt a Packers team trying for its second consecutive Super Bowl.

Fantasy Impact

Jennings has been a huge fantasy asset for owners this season, averaging the fourth-most fantasy among active receivers.

Heading into Sunday's game, Jennings had racked up 65 receptions for 929 yards and nine touchdowns, and his chemistry with quarterback Aaron Rodgers has been undeniable.

If Jennings is forced to miss time, breakout star Jordy Nelson will get more looks in the receiving corps, as well as tight end Jermichael Finley and receivers James Jones and Donald Driver.

Who's the Backup?

James Jones or Donald Driver will slide into the No. 2 spot if Jennings is held out of action moving forward.

Rookie Randall Cobb could also receive more looks.

Devastation Scale

I'm going to give this a 7 out of 10.

For most teams, losing a receiver of Jennings' caliber would be crippling.

But quarterback Aaron Rodgers is so good and can spread the ball around to other receivers so effortlessly that the Packers could still win the Super Bowl without Jennings in my mind.

Well-oiled offenses like the Packers and New England Patriots have a way of winning even when their best players aren't on the field.

Timeline for Return

Jennings is currently being listed as "questionable." 

What They're Saying

Tweeted from user Mariaaa Young:

One fantasy owner was particularly irritated:

Tweeter MRGarvey was simply hopeful:

Sounds like a lot of people want Jennings to be alright, even if it's for selfish reasons.

Of course, other NFL teams wouldn't mind Jennings being held out for the rest of the season.
