If somebody is offering you a reasonable trade in fantasy football for Jacksonville Jaguars running back Maurice Jones-Drew now, jump on it.

Jones-Drew, who is ranked 18th in the NFL in rushing yards this season, sustained a sprained foot against the Oakland Raiders in Week 7, and now it's looking like he will miss multiple games, per Adam Schefter of ESPN.

Jones-Drew already hasn't performed the way fantasy owners thought he would coming into the season. After leading the league with 1,606 rushing yards last year, the seven-year pro has 414 rushing yards so far in 2012 to go along with a disappointing 86 receiving yards. This has already hurt Jones-Drew's fantasy value.

Now you throw in the fact that the Jaguars have a running back they trust in third-year pro Rashad Jennings, and MJD's fantasy value falls even further. Jennings racked up over 100 yards from scrimmage last week against the Raiders (44 rushing, 58 receiving), adding a touchdown along the way.

Of course, Jones-Drew's drop in production largely has to due with the fact that the Jaguars simply aren't a good team overall. That's why they are 1-5 and at the bottom of the AFC South this season.

But does it really matter why at this point? If a player isn't putting up good enough numbers in fantasy, what difference does it make?

MJD wasn't getting what fantasy owners bargained for before his injury. Now that he's limited, his value plummets. Those who own him should be furiously seeking trades, hoping to find someone who will give them value.

I'm not saying to just throw away Jones-Drew, but you should definitely be looking for trade partners. He's already shown he's not going to produce at nearly the same level as he has before.
