Jones left Sunday's win over the Chicago Bears after a 6-yard run during the first quarter. Montgomery is the team's second-leading rusher with 273 yards on 71 carries (3.8-yard average). Coach Mike McCarthy said Montgomery is "still going through tests".
The rookie fifth-round pick is the Packers' leading rusher on the season with 370 yards on 70 carries (5.3-yard average) and has had two 100-yard games since he was inserted into the lineup in Week 4 after Ty Montgomery suffered broken ribs. Starting tight end Martellus Bennett then had a mystery injury issue that led the Packers to cut him. With Aaron Jones (MCL) out indefinitely, the Packers' backfield would be down to rookies Jamaal Williams and Devante Mays should Montgomery be unable to play in Week 11 against Baltimore.
Jones' timetable for return makes it possible Jones could miss most of the season. He remained the Packers' featured back even after Montgomery returned from injury, relegating the converted wide receiver to snaps on a situational basis.
Green Bay selected Jones out of UTEP in the fifth round of the 2017 National Football League draft.
