The Jacksonville Jaguars and Leonard Fournette were able to take care of business in a big way against the New York Jets on Sunday as they won, 31-12. Doug Marrone’s football team stepped up and dominated the game to move to 3-1 on the young season. While the win was a good one for the Jaguars, there was a big setback for them as well.

Fournette, the Jaguars’ star running back, went down with a setback to the hamstring injury that had been bugging him since Week 1. He was forced to leave the game and did not return.

According to Marrone in a press conference shared by ESPN, the Jaguars and Fournette are concerned about the setback.

“I’d be bullsh—— if I said no [he wasn’t concerned]. Any time you come back and you get ready to go and all of a sudden you get injured again it’s not a good sign.”

In the two games that Fournette has been able to play this season, he has carried the football 20 times for 71 yards. He has been unable to get into the end zone so far this year.

Fournette is one of the most talented running backs in the NFL when he’s healthy. Jacksonville’s offense relies heavily on Fournette, especially when it comes to taking pressure off of Blake Bortles. With him having to sit out, the offense has not looked quite as good as it did last season.

T.J. Yeldon seems to be the guy that will pick up the slack if Fournette is forced to miss time. He has had some success this season in limited time, but the Jaguars are certainly hoping that Fournette can return to the field soon.

Expect to hear more news about Fournette’s hamstring by the middle of the week. Jacksonville cannot afford to lose Fournette for too much time.
