Eddie Lacy (ankle) to undergo surgery, be placed on injured reserve

Eddie Lacy's season may be over as his ankle injury will require surgery.

Green Bay Packers running back Eddie Lacy's ankle injury will require surgery and he will be placed on the team's injured reserve, the team announced.

Rapoport notes the Packers do not know if Lacy's season is over yet.

Lacy missed practice earlier in the week and was expected to be out for an extended period of time. He finished last Sunday's 30–16 loss to the Dallas Cowboys with 65 yards on 17 carries.
