Washington Redskins safety Brandon Meriweather will be fined but not suspended for his helmet-to-helmet hit Sunday that knocked Green Bay Packers running back Eddie Lacy out of the game with a concussion sources told ESPN.

Meriweather wasn't penalized during the game for the hit on Lacy.

Meriweather suffered a concussion himself later in the game when he led with his helmet to try to tackle Packers running back James Starks. A flag wasn't thrown on that play either.

Meriweather has a history of fines for illegal hits. While a member of the New England Patriots he was fined $50000 in 2010 (later reduced to $40000 on appeal) for hits against defenseless receivers. In 2011 when he was with the Chicago Bears he was fined $20000 for a helmet-to-helmet hit and $25000 for unnecessary roughness.

Redskins coach Mike Shanahan was asked Monday whether he thought the two plays involving Meriweather were legal hits.

"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" he said.

Shanahan said Meriwether is still undergoing tests for his concussion and the Redskins will have a better idea on how he's doing on Wednesday.
