JACKSONVILLE, Fla. - The Jaguars may have two new returners on special teams on Sunday.

Wide receiver/punt returner Rashad Greene (Achilles) and running back/kick returner Corey Grant (toe) are both listed as a questionable heading into the Jaguars' Week 6 matchup against the Chicago Bears.

Greene would be replaced by veteran wide receiver Bryan Walters if he is unable to play in Chicago. Grant's projected replacement is a bit more murky. Running back Denard Robinson would likely make the most sense, but cornerback Josh Johnson also has experience at the position.

Starting free safety Tashaun Gipson (knee) and defensive end Dante Fowler (illness) appear to be good to go for Sunday.

Below is the entire injury report for the Week 6 matchup between the Jaguars and Bears:


QUESTIONABLE: RB Corey Grant (toe), WR Rashad Greene (Achilles), TE Neal Sterling (foot), FS Tashaun Gipson (knee)


QUESTIONABLE: WR Alshon Jeffery (hamstring), WR Eddie Royal (calf), DB Tracy Porter (knee), RB Ka'Deem Carey (hamstring), DB Bryce Callahan (hamstring), LB Sam Acho (ribs), LB Jerrell Freeman (wrist), OL Bobby Massie (ankle), OL Josh Sitton (shoulder), OL Kyle Long (shoulder), TE Zach Miller (ribs), LB Leonard Floyd (calf), LB Willie Young (knee/elbow)

DOUBTFUL: QB Jay Cutler (right thumb), RB Jeremy Langford (ankle), DL Eddie Goldman (ankle)

OUT: DB Deiondre' Hall (ankle)
