Robinson (toe) has been ruled out of the Jaguars' preseason opener against the Chiefs on Saturday, Demetrius Harvey of The Florida Times-Union reports.
Robinson has been dealing with a toe injury since July 31, and since then he's been limited to individual drills. The rookie fifth-round running back is competing against Tank Bigsby and D'Ernest Johnson for the backup spot behind Travis Etienne. Robinson will work to be available for the Jaguars' second preseason game against the Buccaneers on Aug. 17.
