Interim coach Darrell Bevell confirmed that Robinson suffered a torn Achilles in Sunday's loss to the Jets, Michael DiRocco of ESPN.com and John Reid of The Florida Times-Union report.
The non-contact injury Robinson suffered Sunday indeed is a season-ending one, and he'll presumably face a lengthy recovery period. In his absence down the stretch, the Jaguars' available running back options are Dare Ogunbowale, who handled the bulk of the carries following Robinson's Sunday departure, along with Nathan Cottrell and Ryquell Armstead.
