The NFL issued a warning Friday about fighting after a number of recent incidents during training camp.

NFL executive vice president of football operations Troy Vincent sent a memo to all 32 teams reminding players that prohibiting fights during games will be a point of emphasis for officials.

Vincent’s memo, obtained by FOX Sports, reiterates that the 2015 league policy for players tells them “don’t fight, and if a fight breaks out involving other players, stay away.” The memo was sent to team executives, general managers and head coaches.

“These rules are in place for the protection and safety of our players to keep them on the field,” Vincent wrote. “As professionals, no matter how emotional the game becomes, there is nothing that should resort to fighting. Coaches are encouraged to emphasize to players, coaches, and other club personnel who are on the sidelines, that fighting will not be tolerated.

“We greatly appreciate all of your efforts to advance our great game, keep it competitive and professional, and to ensure that it is played at the highest standards.”

The penalty for fighting in a game is 15 yards with a potential ejection if the foul is judged by the referee to be flagrant.

On Tuesday, New York Jets quarterback Geno Smith had his jaw broken in two spots when he was punched in the locker room by teammate IK Enemkpali. Smith underwent surgery Thursday and is expected to be out six to 10 weeks.

The Smith-Enemkpali situation is being reviewed as an act addressed by the NFL’s personal-conduct policy under the workplace misconduct clause, according to reports.

Enemkpali was released after the Tuesday incident and then claimed off waivers the next day by the Buffalo Bills, who are coached by Rex Ryan, formerly with the Jets when they drafted him in 2014.

Tempers flared at the Carolina Panthers’ training camp on Monday when quarterback Cam Newton and cornerback Josh Norman ended up in a fight. The incident occurred when Norman intercepted Newton two plays into a team drill.

The joint practice last Saturday between the Houston Texans and Washington Redskins was disrupted by a series of brawls. Several fights broke out on two separate practice fields at the Redskins’ training camp facility in Richmond, Va.
