The NFL has warned all 32 teams, making it clear confronting officials would not be tolerated and all teams have to display better on-field behavior. Players could face fines or suspensions if found misbehaving.

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

The collection of small college officials working the games has drawn severe criticism from those on the field. Monday's game between the Falcons and Broncos underlined the matter, with Broncos coach John Fox and defensive coordinator Jack Del Rio engaging in heated arguments with officials.

Ray Anderson, NFL executive vice president, singled out Monday night's game on having examples of "unacceptable behavior." He didn't quite specify which incidents in the Atlanta Falcons' victory over Denver crossed the line, but the Broncos coach John Fox and defensive coordinator Jack Del Rio both had heated arguments with the officials.

An exasperated Anderson said, "We're not going to tolerate it." He further added that flags, fines and suspensions were possible for coaches or players who crossed the line.

Many among the audiences supported the decision of NFL and they claimed that players and coaches are celebrities. Many of them have got the status of 'Role Model' for the younger generations. In such a scenario, if players and coaches will indulge in misbehavior, then it will present a wrong precedence for the young sports lovers.

NFL has taken the disrespectful confrontations of some players and coaches very seriously and it is believed that its warning will have a positive impact on the overall game and the audiences would love to see better behaved players on the field. With the NFL determined to ensure fair play it's interesting to see how teams, managers and coaches respond to the warnings.

Earlier, the NFL Referees Association had told the team owners, general managers and coaches to "send a message that everyone has a responsibility on respect for the game," NFL Executive Vice President Ray Anderson said, according to the league's website.
