He sustained the injury in Sunday's game against the Falcons and did not return. The injury did not look great and Lacy was in some pain after going down. He finished Sunday's game with 65 yards on 20 carries to go with three catches for 25 yards on five targets. Lacy added a one-yard run in the first quarter of the win.
The team may give him some further evaluation to check on the ligaments in his ankle, but there is nothing concrete at this time.
James Starks took over as the featured back with seven carries for 19 yards.
Fantasy impact: Jonathan Franklin is out for the season, so it would be all Starks should Lacy miss time. Fantasy owners really have no choice but to add Starks in almost any league. The Packers get a leaky run D when they travel to AT&T Stadium to take on the Cowboys. Starks would be an RB2 in that game.
