Brandon Meriweather was suspended by the NFL for too many hits to the head, so he publicly stated this week he'll start aiming for players' knees instead.

The league and the NFL Players Association then reminded the Washington Redskins safety that's not acceptable, either.

In a statement posted on the NFLPA's website, union executive director DeMaurice Smith said he's spoken with Meriweather about the importance of safe play.

"He is passionate about the game, and I know he is sorry for what he said," Smith said. "He is concentrating on helping his team win the rest of the season. Brandon knows that all players have a responsibility to each other and to play within the rules of the game.”

Merton Hanks, the league's VP of football operations, also had a chat with Meriweather.

“We have no higher priority than player health and safety," Hanks said in a statement to FOX Sports. "Recent comments by Brandon Meriweather call into question his commitment to that objective and were clearly inappropriate. I have spoken with Brandon, and he understands what is expected of him as an NFL player, which includes avoiding any acts that unnecessarily and unreasonably endanger the welfare of other players."

Meriweather was initially suspended for two games following a pair of penalties in an Oct. 20 game against the Chicago Bears. Ted Cottrell, the appeals officer jointly appointed by the NFL and NFLPA, reduced the suspension to one game -- Sunday's loss to the Denver Broncos. Meriweather is slated to return to action this weekend against the San Diego Chargers.
