Eddie Lacy's status remains uncertain

GREEN BAY, Wis. -- Green Bay Packers running back Eddie Lacy’s status for Sunday’s game at Cincinnati remains uncertain.

Packers coach Mike McCarthy did not provide an update Monday on Lacy, who was knocked out of Sunday’s game against the Washington Redskins with a concussion he suffered after taking a hit from safety Brandon Meriweather.

It was unclear how far along in the concussion protocol Lacy was on Monday, however. He was not at the team meeting.

Teams do not have to provide injury reports until Wednesday.

“I stand up here on Mondays and a lot of the times there’s more testing going on,” McCarthy said. “And based on the protocol of the league, we’re going to follow it, so we’ll have an update for you on Wednesday.”

Meriweather wasn’t penalized for the hit on Lacy.

“The Washington safety definitely led with his helmet, so I know that’s not what we’re looking for,” McCarthy said.

Meriweather delivered another questionable helmet hit -- the second one on running back James Starks actually caused Meriweather to leave with a concussion.

“Same thing, different result,” McCarthy said.

Redskins coach Mike Shanahan had a different opinion of the plays during his news conference on Monday.

“To be honest with you, on the first one it looked like the running back was kind of going downhill and when Brandon went for the tackle it looked to me like it was perfect. And then all of a sudden when [Lacy] ducked his head, I couldn’t tell -- I didn't see the TV copy, I just saw the video -- and that’s exactly where the contact was,” Shanahan said. “The second one on the sidelines, that’s what you’re supposed to do. That’s a legal hit.”

Update: ESPN’s Chris Mortensen reported that the NFL is reviewing Meriweather’s hit on Lacy.
