Jones (hamstring) is listed as doubtful for Sunday's contest against the 49ers.
An injury-plagued training camp and preseason for Jones has followed him into the regular season. Currently, a hamstring issue has been the culprit, keeping him out of all three practices this week. Assuming Jones is unable to suit up Sunday, the Bears will rely on Darnell Mooney, Equanimeous St. Brown, Byron Pringle, Dante Pettis and Ihmir Smith-Marsette at wide receiver.
