Jaguars coach Doug Marrone said he's very concerned about RB Leonard Fournette experiencing hamstring tightness on Sunday. This was Fournette's first game back since he got injured during the season opener and he left the game late in the first half against the Jets. "I’d be bullsh------ if I said no [he wasn't concerned]," Marrone said. "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."
