JACKSONVILLE – What was known became official Friday.
Running back Leonard Fournette and cornerback D.J. Hayden, both unofficially ruled out earlier in the week for the Jaguars' game against the Kansas City Chiefs, on Friday were officially listed as being out for the game.
The news was better on the rest of the injury front, with all other active Jaguars starters expected to play Sunday against the NFL's No. 1-ranked scoring offense.
"Obviously this is going to be a great challenge against this team," Marrone said Friday afternoon as the Jaguars (3-1) prepared to play the Chiefs (4-0) at Arrowhead Stadium in Kansas City, Missouri, Sunday at 1 p.m.
"It's a great football team we're playing, and we're playing in them in their home stadium, which is one of the toughest places to play in the league. There's a lot going on. We have to get ourselves ready and we have to get ourselves focused."
The Jaguars on Friday added rookie cornerback/special teams player Tre Herndon (hamstring) to the injury report as questionable, but all other injured players were removed from the game status report and are expected to play Sunday.
Other injured players this week: running back T.J. Yeldon (ankle), guard Andrew Norwell (foot), center Brandon Linder (knee/back), guard A.J. Cann (triceps), right tackle Jermey Parnell (knee), tight end Austin Seferian-Jenkins (core muscle) and end Calais Campbell (ankle). All were listed as practicing full Friday.
Marrone on Friday also discussed the potential for rain in Sunday, with forecasts calling for an 80-to-90 percent chance of rain at kickoff.
"We're ready for it," Marrone said. "I guess it goes back to college for me. I'm a big wet-ball-drill guy, so we practice out in the rain."
Marrone added with a smile, "I'm a mudder myself, so you hope the team takes that kind of characteristic."
