NFL warns teams about confronting replacement officials

NEW YORK - The NFL has warned teams that it won't tolerate confrontational behavior toward replacement officials.

NFL.com said on Thursday night that senior league officials called owners, general managers and coaches from all 32 teams to tell them that respect for the game demands better on-field behavior.

NFL executive vice president Ray Anderson singled out Monday night's game for having examples of "unacceptable behavior."

He didn't specify which incidents in the Atlanta Falcons' victory over Denver crossed the line, but Broncos coach John Fox and defensive coordinator Jack Del Rio both had heated arguments with officials.

Anderson said, "We're not going to tolerate it."

He said flags, fines and suspensions are possible for coaches or players who crossed the line.

The NFL locked out the regular officials in June and contract negotiations have broken down.
