The NFL sent a memo Wednesday to all 32 teams warning of fines, suspensions and loss of draft picks if the league determines players faked injuries during a game. Yet several players admit it's an accepted practice, and some coaches hinted they are not above condoning phony injuries if it provides a competitive edge.

"I've been places where it has been (taught)," said Browns linebacker Scott Fujita, a member of the players' union executive committee. "They have a name for it and I've been places where it's been pre-called. I've been places where it's one player who has been designated. Maybe I'm getting everyone in trouble, but I'm just being honest."

While calling it "real bush league" -- no pun intended -- Dolphins running back Reggie Bush said a coach "just designates a guy who fakes an injury. It's usually not a captain of the team. It's a guy who's expendable."

In the memo obtained by ESPN and The Associated Press, the NFL reminded teams of league policy that calls on coaches to discourage the practice, and that there was no specific rule on the topic.

However, two days after there was speculation the Giants' Deon Grant faked an injury against the Rams during the Monday night game, the NFL is warning of disciplinary action.

"It's always been in the game," Ravens All-Pro safety Ed Reed said. "It's all tactical stuff you need to use. Whatever it takes. ... If you're tired, you're tired. You get a break however you can."

Added 49ers running back Frank Gore: "Hey, I feel if it helps, do it. I'm bound to do it. Whatever it takes to win ..."

Rams coach Steve Spagnuolo said Tuesday the team notified the league office that it suspected the Giants were feigning injuries in St. Louis' 28-16 loss. Rams quarterback Sam Bradford said it was obvious the Giants were just buying time, with St. Louis running a no-huddle offense.

"They couldn't get subbed, they couldn't line up," Bradford said. "Someone said, 'Someone go down, someone go down,' so someone just went down and grabbed a cramp."
