Jaguars unsure how much time Fournette will miss

Jacksonville Jaguars running back Leonard Fournette left Sunday's game against the New York Jets after re-aggravating a hamstring injury.

The initial injury cost Fournette two games of this season, and the Jaguars are unsure how long he'll be out with the re-injury.

"Probably go back to when he first hurt it. I don't know how long it'll be. We'll just take it day by day," head coach Doug Marrone said at his Monday press conference.

"It's the same thing. There's a thing that's just pulling at it, it's legit, there is something there. We've just got to do everything we can to get that out. ... That's all I know."

Marrone was asked whether Fournette would be expected to miss another two games.

"I don't know. I really don't know. ... Those injuries are tough," he said.

Jacksonville owns a 3-1 record this season despite getting just 20 carries from Fournette split between appearances in Week 1 and Week 4 wins.
