Jones (ankle) is listed as questionable for Sunday's game against the Eagles.
Jones is coming off a 10-catch performance in Jacksonville's Week 3 win over the Chargers, so he'll be sorely missed if he's unable to play Week 4. Marvin Jones would become Jacksonville's clear-cut No. 2 wide receiver behind Christian Kirk if Zay Jones doesn't play, while more targets could go to tight end Evan Engram or gadget guy Jamal Agnew.
