The strongest bone in the human body is the femur while the semintendinosous, semimembranosous, and the biceps femoris are part of the muscle group known as the hamstring muscles that surround this important bone in the leg. According to the American College Sports Medicine the hamstring muscles are often the most injured part of the lower extremity when it comes to sports, particularly soccer and football. 

The NFL has had its fair share of hamstring injuries this year, with the Jaguars’ Leonard Fournette nursing a hamstring issue suffered Week 3 and has yet to be cleared to return. According to Florida Football Insiders, the Jaguars may rest Fournette and his lingering hamstring issue through the Week 9 bye in hopes to having him available for Week 10 action. 

The Jaguars backfield has been absolutely depleted by injury this year. Fournette was the starter going into the season, with backups T.J. Yeldon and Corey Grant vying for snaps behind the second year runner from LSU. Grant, who averaged an outrageous 8.3 yards per carry in 2017 subsequently being hyped up by offensive coordinator Nathaniel Hackett to get more touches this season, suffered a Lisfranc foot injury in Week 5 against the Chiefs and headed to injured reserve for the rest of 2018. This leaves Yeldon to do the heaving lifting as Fournette continues to nurse his hamstring injury. 

Yeldon has produced three solid weeks in PPR formats with back to back 20+ point efforts the past two weeks since taking over RB1 duties. Yeldon was drafted in 2015 as a potential bell cow back, but has never really materialized into one. Yeldon now grabs the reigns again as the bell cow back, this being a contract year, and will look showcase himself with Fournette out and possibly cash in this offseason by resigning with the Jaguars or testing free agency. Fantasy owners can possibly buy low on Yeldon now, hoping he signs with a running back needy team who will view him as a Jerick McKinnon type free agent.

With Grant now on IR and Fournette possibly out until Week 10, the Jaguars signed former All-Pro Jamaal Charles to a contract earlier this week to help fill the void in the backfield. Charles was known for his electrifying runs as a member of the Kansas City Chiefs back in his prime. Now 31, Charles will be on his third team in as many years. Last year Charles signed a one year deal with the Denver Broncos to help solidify a backfield also hampered by the injury bug at the time. Charles showed he still had some gas left in the tank, as he averaged 4.3 yards per carry on just 69 attempts. Charles did suffer an ACL injury in 2015, so the signing is a calculated risk by the Jaguars.  Fantasy owners should be able to add Charles for free in the free agent pool as he was available in 96 percent of leagues prior to his signing.

The Jaguars will deploy a mix of Yeldon and Charles for the next handful of weeks and will look to get back on track in the win column this coming week against the Dallas Cowboys at AT&T Stadium in Arlington, Texas.
