Don't count out Eddie Lacy from Sunday's game just yet. With two days to go before the Green Bay Packers take the field in Cincinnati for their Week 3 matchup with the Bengals Lacy hasn't been medically cleared from the NFL's concussion protocol. However the Packers haven't given up hope that their rookie running back will be ready in time. "Eddie Lacy's situation frankly I thought that there was a really good chance for him to practice today (Friday) based on his diagnosis after the game" coach Mike McCarthy said. "Once again our doctors are going through the procedures and trusting the information. We still have time and the doctors are in charge of evaluating going through the protocol. "I know that Eddie Lacy wants to play so we'll see what happens." Lacy suffered a concussion on his first carry of Green Bay's Week 2 home win over the Washington Redskins. He hasn't practiced all week and is officially listed as questionable for Sunday's game at Cincinnati. "Well it's not ideal; it's not ideal for a rookie to go through the week without any preparation and then play in the game no question about it" McCarthy said. "I'm not excited about it. We want 46 players that we feel give us the best chance to beat the Cincinnati Bengals. "When the plan was put together on Monday and Tuesday Eddie Lacy was part of that plan based on the information given by the medical staff. If that's not the case it's always a medical decision first. You have secondary plans and we've done that but in the primary plan Eddie was part of the thinking." If Lacy isn't cleared it's possible that the Packers would only have two healthy running backs. Even fullback John Kuhn is doubtful with a hamstring injury leaving Green Bay with just James Starks and fourth-round pick Johnathan Franklin.
